A more extensive definition and analysis with references is contained in the Stanford Encyclopedia of Philosophy http://plato.stanford.edu/entries/euthanasia-voluntary/</ref>

==Background== ==Background==
At the beginning of the twentieth century, the sterilisation of people carrying what were considered to be hereditary defects and in some cases those exhibiting what was thought to be hereditary "antisocial" behaviour, was a respectable field of medicine. ], ], ] and the ] had passed laws enabling ]. Studies conducted in the 1920s ranked Germany as a country that was unusually reluctant to introduce sterilisation legislation.{{sfn|Hansen|King|2013|p=141}} In his book '']'' (1924), Hitler wrote that one day racial hygiene "will appear as a deed greater than the most victorious wars of our present bourgeois era".{{sfn|Hitler|p=447}}{{sfn|Padfield|1990|p=260}}
The T4 programme is thought to have developed from the Nazi Party's policy of "]", the belief that the German people needed to be "cleansed" of "racially unsound" elements, which included people with disabilities. Historians {{weasel-inline|date=April 2014}} consider the euthanasia programme as related to the evolution in policy that ordered the extermination of the Jews of Europe. {{citation needed|date=April 2014}}


In July 1933, the "]" prescribed ] for people with conditions thought to be hereditary, such as schizophrenia, ], ] and "imbecility". Sterilisation was also legalised for chronic alcoholism and other forms of social deviance. The law was administered by the Interior Ministry under ] through special ]s ({{lang|de|Erbgesundheitsgerichte}}), which examined the inmates of nursing homes, asylums, prisons, aged-care homes and special schools, to select those to be sterilised.{{sfn|Evans|2005|pp=507–508}} It is estimated that 360,000 people were sterilised under this law between 1933 and 1939.<ref>{{cite web |title=Forced Sterilization |website=] |url=https://www.ushmm.org/learn/students/learning-materials-and-resources/mentally-and-physically-handicapped-victims-of-the-nazi-era/forced-sterilization |archive-url=https://web.archive.org/web/20190104162134/https://www.ushmm.org/learn/students/learning-materials-and-resources/mentally-and-physically-handicapped-victims-of-the-nazi-era/forced-sterilization |access-date=21 December 2022 |archive-date=2019-01-04 }}</ref>
Racial hygienist ideas and ] were widespread in many western countries in the early 20th century. Emerging information about genetic diseases and conditions led people to think they could prevent their being passed on to future generations. The ] movement had many followers among educated people, being ]. The idea of sterilising those carrying hereditary defects or exhibiting what was thought to be hereditary antisocial behaviour was widely accepted. The United States, Sweden, Switzerland and other countries also passed laws authorizing sterilization of certain classes of people. For example, between 1935 and 1975, Sweden sterilised 63,000 people on eugenic grounds.<ref>Evans, 514</ref>

The Nazis began to implement "racial hygiene" policies as soon as they came to power. The July 1933 "Law for the Prevention of Hereditarily Diseased Offspring" prescribed ] for people with a range of conditions thought to be hereditary, such as ], ], ] and "imbecility".

It is estimated that 360,000 people were sterilised under this law between 1933 and 1939. Within the Nazi administration, some suggested that the programme should be extended to people with physical disabilities, but such ideas had to be expressed carefully, given that one of the most powerful figures of the regime, ], had a deformed right leg.<ref>This was the result either of ] or ].

After 1937, the acute shortage of labour in Germany arising from the demands of the crash rearmament programme meant that anyone capable of work was deemed to be "useful" and thus exempted from the law. The rate of sterilisation declined.<ref>Evans (2005): 508</ref>

On 18 August 1939, three weeks after the killing of the boy, the ''Reich Committee for the Scientific Registering of Hereditary and Congenital Illnesses'' was established to register sick children or newborns identified as defective.

He intended, he wrote, "in the event of a war radically to solve the problem of the mental asylums".<ref>Kershaw, II, 256</ref> The initiation of war also provided Hitler with the possibility of carrying out a policy he had long favoured.
The German eugenics movement had an extreme wing even before the Nazis came to power. As early as 1920, ] and ] advocated killing people whose lives were "unworthy of life" ({{lang|de|lebensunwertes Leben}}).

This issue assumed new urgency in wartime according to the Nazi regime. People with severe disabilities, even if sterilised, still needed institutional care. They occupied places in facilities which, during war, would be needed for wounded soldiers and people evacuated from bombed cities. They were housed and fed at the expense of the state, and took up the time of doctors and nurses. The Nazis barely tolerated this support in peacetime. Few supported care for such people in wartime, especially in the last years of World War II when conditions overall were so terrible in Germany. As a leading Nazi doctor, Dr. ], said: "The idea is unbearable to me that the best, the flower of our youth must lose its life at the front in order that feebleminded and irresponsible asocial elements can have a secure existence in the asylum".<ref name="Lifton, 63">Lifton (1986): 63</ref>

During the 1930s, the Nazi Party carried out a campaign of propaganda in favour of "euthanasia".

The official programme for killing adults with mental or physical disabilities began with a letter from Hitler issued in October 1939.

As with the child inmates, the adult cases were assessed by a panel of experts, working at the Tiergartenstraße offices. The experts were required to make their judgments solely on the basis of the reports, rather than on detailed medical histories, let alone examinations.

They were moved again to "special treatment" ('']'') centres. Families were sent letters explaining that owing to wartime regulations, it was not possible for them to visit relatives in these centres. Most of these patients were killed within 24 hours of arriving at the centres, and their bodies cremated.<ref name = "Lifton (1986): 71" /> For every person killed, a death certificate was prepared, giving a false but plausible cause of death.

When some institutions refused to co-operate, teams of T4 doctors (or Nazi medical students) visited and compiled the lists, sometimes in a haphazard and ideologically motivated way.{{sfn|Lifton|1986|pp=66–67}} During 1940, all Jewish patients were removed from institutions and killed.{{sfn|Browning|2005|p=191}}{{sfn|Padfield|1990|pp=261, 303}}{{sfn|Lifton|1986|p=77}}{{efn|According to Lifton, most Jewish inmates of German mental institutions were dispatched to Lublin in Poland in 1940 and killed there.{{sfn|Lifton|1986|p=77}}}}


As with child inmates, adults were assessed by a panel of experts, working at the {{lang|de|Tiergartenstraße}} offices. The experts were required to make their judgements on the reports, not medical histories or examinations. Sometimes they dealt with hundreds of reports at a time. On each they marked a '''+''' (death), a '''-''' (life), or occasionally a '''?''' meaning that they were unable to decide. Three "death" verdicts condemned the person and as with reviews of children, the process became less rigorous, the range of conditions considered "unsustainable" grew broader and zealous Nazis further down the chain of command increasingly made decisions on their own initiative.{{sfn|Lifton|1986|p=67}}
During 1940, the centres at Brandenburg, Grafeneck and Hartheim killed nearly 10,000 people each, while another 6,000 were killed at Sonnenstein. In all, about 35,000 people were killed in T4 operations that year. Operations at Brandenburg and Grafeneck were wound up at the end of the year, partly because the areas they served had been cleared and partly because of public opposition. In 1941, however, the centres at Bernburg and Sonnenstein increased their operations, while Hartheim (where Wirth and ] were successively commandants) continued as before. As a result, another 35,000 people were killed before August 1941, when the T4 programme was officially shut down by Hitler. Even after that date, however, the centres continued to be used to kill concentration camp inmates: eventually some 20,000 people in this category were killed.<ref>These figures come from the article ] on the German Misplaced Pages, which sources them to Ernst Klee, ''"Euthanasie" im SS-stadt: Die "Vernichtung lebensunwerten Leben"'' ("Euthanasia" in the SS-state: The extermination of "life unworthy of life"), Frankfurt, 1983</ref>


==Gassing==
In 1971 the Austrian-born journalist ] conducted a series of interviews with ], who was in prison in ] after having been convicted of co-responsibility for killing 900,000 people as commandant of the ] and ] ]s in Poland. Stangl gave Sereny a detailed account of the operations of the T4 programme based on his time as commandant of the killing facility at the Hartheim institute.<ref>Sereny (1983): 41–90</ref> He described how the inmates of various asylums were removed and transported by bus to Hartheim.

They were told they were at a special clinic where they would receive improved treatment, and were given a brief medical examination on arrival. They were induced to enter what appeared to be a shower block, where they were gassed with ] (this ruse was later used on a much larger scale at the extermination camps).
The first gassings in Germany proper took place in January 1940 at the Brandenburg Euthanasia Centre. The operation was headed by Brack, who said "the needle belongs in the hand of the doctor".{{sfn|Annas|Grodin|1992|p=25}} Bottled pure carbon monoxide gas was used. At trials, Brandt described the process as a "major advance in medical history".{{sfn|Lifton|1986|pp=71–72}} Once the efficacy of the method was confirmed, it became standard and was instituted at a number of centres in Germany under the supervision of Widmann, Becker and ] – a ] officer who later played a prominent role in the ] (extermination of Jews) as commandant of newly built ]s in occupied Poland. In addition to Brandenburg, the killing centres included ] in Baden-Württemberg (10,824 dead), ] near ] in Austria (over 18,000 dead), Sonnenstein in ] (15,000 dead), ] in Saxony-Anhalt and ] in Hesse (14,494 dead). The same facilities were also used to kill mentally sound prisoners transferred from ]s in Germany, Austria and occupied parts of Poland.

After the official end of the euthanasia programme in 1941, most of the personnel and high-ranking officials, as well as gassing technology and the techniques used to deceive victims, were transferred under the jurisdiction of the national medical division of the Reich Interior Ministry. Further gassing experiments with the use of ] ({{lang|de|Einsatzwagen}}) were conducted at ] by Herbert Lange following ]. Lange was appointed commander of the ] in December 1941. He was given three gas vans by the ] (RSHA), converted by the Gaubschat GmbH in Berlin{{sfn|Beer|2015|pp=403–417}} and before February 1942, killed 3,830 ] and around 4,000 ], under the guise of "resettlement".{{sfn|Ringelblum|2013|p=20}} After the ], implementation of gassing technology was accelerated by Heydrich. Beginning in the spring of 1942, three killing factories were built secretly in east-central Poland.

Hitler and his aides were aware from the start that a programme of killing large numbers of Germans with disabilities would be unpopular with the German public. Although Hitler had a fixed policy of not issuing written instructions for policies relating to what would later be classed by the ] and other parties as ], he made an exception when he provided Bouhler and Brack with written authority for the T4 programme in his confidential October 1939 letter. This was apparently to overcome opposition within the German state bureaucracy. The Justice Minister, ], had to be shown Hitler's letter in August 1940 to gain his cooperation.<ref name="Kershaw, II, 253"/>


In January 1939, Brack commissioned a paper from Professor of ] at the ], Joseph Mayer, on the likely reactions of the churches in the event of a state euthanasia programme being instituted. Mayer{{snd}}a longstanding euthanasia advocate{{snd}}reported that the churches would not oppose such a programme if it was seen to be in the national interest. Brack showed this paper to Hitler in July and it may have increased his confidence that the "euthanasia" programme would be acceptable to German public opinion.{{sfn|Kershaw|2000|p=259}} Notably, when Sereny interviewed Mayer shortly before his death in 1967, he denied that he formally condoned the killing of people with disabilities but no copies of this paper are known to survive.{{sfn|Sereny|1983|p=71}}
Hitler told Bouhler at the outset that "the Führer's Chancellery must under no circumstances be seen to be active in this matter."<ref name = "Padfield 261" /> He recommended caution in Catholic areas, which after the annexations of Austria and the ] in 1938 included nearly half the population of Greater Germany; public opinion could be expected to be hostile. In March 1940 a confidential report from the ] in Austria warned that the killing programme must be implemented with stealth "in order to avoid a probable backlash of public opinion during the war".<ref>Padfield, 304</ref>


Opposition persisted within the bureaucracy. ], a district judge and member of the ], wrote to Gürtner protesting that the T4 programme was illegal (since no law or formal decree from Hitler had authorised it).

===Exposure===
In the ] between Germany and the ], the Catholic Church had agreed to withdraw from all political activity. In 1933 the prospect of state-sanctioned mass killing of German citizens had not occurred to the Church. Such a challenge to fundamental Christian belief in the sanctity of human life posed a serious dilemma for German Catholics. In 1935 the Church had protested in a private memorandum against proposals to pass a law legalising euthanasia: this was one reason the law was not enacted.{{Citation needed|date=February 2009}} ], the ] accused the government of breaking the law and publicly condemned the policy. Fr ] protested the policy to the Nazis chief medical officer.<ref>http://www.catholicherald.co.uk/features/2011/01/19/ten-catholic-heroes-of-the-holocaust/</ref> The regime took the program underground.<ref>http://www.yadvashem.org/yv/en/education/courses/life_lessons/pdfs/lesson8_4.pdf</ref>
In the towns where the killing centres were located, some people saw the inmates arrive in buses, saw smoke from the crematoria chimneys and noticed that the buses were returning empty. In Hadamar, ashes containing human hair rained down on the town and despite the strictest orders, some of the staff at the killing centres talked about what was going on. In some cases families could tell that the causes of death in certificates were false, e.g. when a patient was claimed to have died of ], even though his appendix had been removed some years earlier. In other cases, families in the same town would receive death certificates on the same day.{{sfn|Lifton|1986|p=75}} In May 1941, the Frankfurt County Court wrote to Gürtner describing scenes in Hadamar, where children shouted in the streets that people were being taken away in buses to be gassed.{{sfn|Sereny|1983|p=58}}


] in 1920]]
In January 1939, ] commissioned a paper from Dr ], Professor of ] at the ], on the likely reactions of the churches in the event of a state euthanasia programme being instituted. Mayer&nbsp;– a longstanding euthanasia advocate&nbsp;– reported that the churches would not oppose such a programme if it was seen to be in the national interest. Brack showed this paper to Hitler in July, and it may have increased his confidence that the "euthanasia" programme would be acceptable to German public opinion.<ref name="Kershaw, II, 259"/> (When Gitta Sereny interviewed Mayer shortly before his death in 1967, he denied that he had approved of killing people with disabilities, but since no copies of this paper are known to survive, this cannot be determined.)<ref>Sereny (1983): 71</ref> This turned out not to be the case. The T4 programme was the sole example of an action by the Nazi regime which provoked large-scale public protests.
During 1940, rumours of what was taking place spread and many Germans withdrew their relatives from asylums and sanatoria to care for them at home, often with great expense and difficulty. In some places doctors and psychiatrists co-operated with families to have patients discharged or if the families could afford it, transferred them to private clinics beyond the reach of T4. Other doctors "re-diagnosed" patients so that they no longer met the T4 criteria, which risked exposure when Nazi zealots from Berlin conducted inspections. In ], Professor ] managed to save nearly all of his patients.{{sfn|Lifton|1986|pp=80, 82}} Lifton listed a handful of psychiatrists and administrators who opposed the killings; many doctors collaborated, either through ignorance, agreement with Nazi eugenicist policies or fear of the regime.{{sfn|Lifton|1986|pp=80, 82}}


Protest letters were sent to the Reich Chancellery and the Ministry of Justice, some from Nazi Party members. The first open protest against the removal of people from asylums took place at ] in ] in February 1941 and others followed. The SD report on the incident at Absberg noted that "the removal of residents from the Ottilien Home has caused a great deal of unpleasantness" and described large crowds of Catholic townspeople, among them Party members, protesting against the action.{{sfn|Lifton|1986|p=90}} Similar petitions and protests occurred throughout Austria as rumours spread of mass killings at the Hartheim Euthanasia Centre and of mysterious deaths at the children's clinic, {{lang|de|Am Spiegelgrund}} in Vienna. Anna Wödl, a nurse and mother of a child with a disability, vehemently petitioned to Hermann Linden at the Reich Ministry of the Interior in Berlin to prevent her son, Alfred, from being transferred from Gugging, where he lived and which also became a euthanasia center. Wödl failed and Alfred was sent to {{lang|de|Am Spiegelgrund}}, where he was killed on 22 February 1941. His brain was preserved in formaldehyde for "research" and stored in the clinic for sixty years.{{sfn|NEP|2017}}
It was impossible to keep the T4 programme secret: thousands of doctors, nurses and administrators were involved in it, and the majority of those killed had families who were actively concerned about their welfare. Despite the strictest orders to maintain secrecy, some of the staff at the killing centres talked about what was going on. In some cases families could tell that the causes of death in certificates were false, e.g. when a patient was claimed to have died of ], even though his appendix had been surgically removed some years earlier. In other cases, several families in the same town would receive death certificates on the same day. In the towns where the killing centres were located, many people saw the inmates arrive in buses, saw the smoke from the crematoria chimneys, noticed that no bus-loads of inmates ever left the killing centres, and drew the correct conclusion.

During 1940 rumours of what was taking place spread, and many Germans withdrew their relatives from asylums and sanatoria to care for them at home&nbsp;– often with great expense and difficulty. In some places doctors and psychiatrists co-operated with families to have patients discharged, or, if the families could afford it, had them transferred to private clinics where the reach of T4 did not extend. Other doctors agreed to "re-diagnose" some patients so that they no longer met the T4 criteria. This risked exposure when the Nazi zealots from Berlin conducted inspections. In ], Professor ] managed to save nearly all of his patients.<ref>Lifton (1986): 82. Creutzfeldt is also remembered as the co-discoverer of ]</ref> For the most part, however, doctors co-operated with the programme, either from ignorance as to its true nature, agreement with Nazi eugenicist policies, or fear of the regime.<ref>Lifton (1986): 80.

During 1940 protest letters were sent to the Reich Chancellery and the Ministry of Justice, some of them from Nazi Party members. The first open protest against the removal of people from asylums took place at ] in ] in February 1941, and others followed. The SD report on the incident at Absberg noted that "the removal of residents from the Ottilien Home has caused a great deal of unpleasantness", and described large crowds of Catholic townspeople, among them Party members, protesting against the action.<ref>Lifton (1986): 90</ref> Opposition to the T4 policy sharpened after the ] in June 1941, because the war in the east produced for the first time large-scale German casualties, and the hospitals and asylums began to fill up with maimed and disabled young German soldiers. Rumours began to circulate that these men would also be subject to "euthanasia."{{Citation needed|date=July 2011}}

===Church action===
During 1940 and 1941 some Protestant churchmen protested privately against T4, but none made any public comment. Bishop ], presiding the ], wrote a strong letter to Interior Minister Frick in March 1940. On 4 December 1940 Reinhold Sautter, Supreme Church Councillor of Württemberg's State Church, reproached the Nazi Ministerial Councillor Eugen Stähle for the murders in ]. Stahle retorted with the Nazi government opinion, that "The fifth commandment: ], is no commandment of God but a Jewish invention" and no longer had any validity.<ref>Schmuhl (1987): p. 321</ref>

Others who privately protested were the Lutheran theologian ], director of the ] for epileptics at ]; and Pastor ], director of the ] near Berlin. Both used their connections with the regime to negotiate exemptions for their institutions: Bodelschwingh negotiated directly with Brandt and indirectly with ], whose cousin was a prominent psychiatrist. Braune had meetings with Justice Minister Gürtner, who was always dubious about the legality of the programme. Gürtner later wrote a strongly worded letter to Hitler protesting against it; Hitler did not read it, but was told about it by Lammers.<ref>Lifton (1986): 90–92.</ref> In general, the leaders of the Protestant church were more enmeshed with the Nazi regime than was the case for Catholics, and they were unwilling to criticise its actions.<ref>Sereny (1983): 69, 74</ref>


The Lutheran theologian ] (director of the ] for Epilepsy at ]) and Pastor Paul-Gerhard Braune (director of the Hoffnungstal Institution near Berlin) protested. Bodelschwingh negotiated directly with Brandt and indirectly with ], whose cousin was a prominent psychiatrist. Braune had meetings with Gürtner, who was always dubious about the legality of the programme. Gürtner later wrote a strongly worded letter to Hitler protesting against it; Hitler did not read it but was told about it by Lammers.{{sfn|Lifton|1986|pp=90–92}} Bishop ], presiding over the ], wrote to Interior Minister Frick in March 1940 and that month a confidential report from the {{lang|de|]}} (SD) in Austria, warned that the killing programme must be implemented with stealth "...to avoid a probable backlash of public opinion during the war".{{sfn|Padfield|1990|p=304}} On 4 December 1940, Reinhold Sautter, the Supreme Church Councillor of the Württemberg State Church, complained to the Nazi Ministerial Councillor Eugen Stähle against the murders in Grafeneck Castle. Stähle said "The fifth commandment Thou shalt not kill, is no commandment of God but a Jewish invention".{{sfn|Schmuhl|1987|p=321}}
The Catholic Church, which since 1933 had pursued a policy of avoiding confrontation with the Nazi regime in the hope of preserving its core institutions, became increasingly unable to keep silent in the face of mounting evidence about the killing of inmates of hospitals and asylums. Leading Catholic churchmen, led by Cardinal ] of ], wrote privately to the government protesting against the policy. In July 1941 the Church broke its silence when a pastoral letter from the bishops was read out in all churches, declaring that it was wrong to kill (except in self-defence or in a morally justified war).<ref name = "Kershaw II 427">Kershaw, II, 427</ref> This emboldened Catholics to make more outspoken protests.


Bishop Heinrich Wienken of Berlin, a leading member of the ], was selected by the ] episcopal synod to represent the views of the Catholic Church in meetings with T4 operatives. In 2008, ] wrote
A few weeks after the pastoral letter was read out, the Catholic ] in ], ], publicly denounced the T4 programme in a sermon. He telegrammed his text to Hitler, calling on

"We are talking about men and women, our compatriots, our brothers and sisters. Poor unproductive people if you wish, but does this mean that they have lost their right to live?"<ref>Lifton (1986): 93</ref></blockquote>
{{blockquote|Wienken seems to have gone partially native in the sense that he gradually abandoned an absolute stance based on the Fifth Commandment in favour of winning limited concessions regarding the restriction of killing to 'complete idiots', access to the sacraments and the exclusion of ill Roman Catholic priests from these policies.{{sfn|Burleigh|2008|p=261}}}}


Despite a decree issued by the Vatican on 2 December 1940 stating that the T4 policy was "against natural and positive Divine law" and that "The direct killing of an innocent person because of mental or physical defects is not allowed", the Catholic Church hierarchy in Germany decided to take no further action. Incensed by the Nazi appropriation of Church property in ] to accommodate people made homeless by an air raid, in July and August 1941, the ], ], gave four sermons criticising the Nazis for arresting ]s, confiscating church property and for the euthanasia program.{{sfn|Ericksen|2012|p=111}}{{sfn|Evans|2009|p=110}} Galen sent the text to Hitler by telegram, calling on
Historian Robert Lifton says of this sermon:
<blockquote>"This powerful, populist sermon was immediately reproduced and distributed throughout Germany&nbsp;– indeed, it was dropped among German troops by British Royal Air Force pilots. Galen's sermon probably had a greater impact than any other statement in consolidating anti-'euthanasia' sentiment."<ref>Lifton (1986): 94</ref></blockquote>Another Bishop, ] of ], also sent protests to Hitler, though not publicly. In August Galen was even more outspoken, broadening his attack to include the Nazi persecution of religious orders and the closing of Catholic institutions. He attributed the heavy allied bombing of Westphalian towns to the wrath of God against Germany for breaking His laws. Galen's sermons were not reported in the German press, but were widely circulated in the form of illegally printed leaflets.<ref name = "Kershaw II 427" /> Local Nazis asked for Galen to be arrested, but Goebbels told Hitler that such action would provoke open revolt in Westphalia.<ref>Kershaw, II, 429</ref>

By August the protests had spread to Bavaria. According to Gitta Sereny, Hitler was jeered by an angry crowd at ]&nbsp;– the only time he was opposed in public during his 12 years of rule.<ref name="Sereny" >Sereny (1983): 59. Sereny did not claim firsthand knowledge of this event. It is apparently based on testimony given by Dr Friedrich Mennecke during a postwar trial. According to Mennecke, Hitler was traveling between Munich and Berlin when his train suddenly stopped at a station. A crowd was watching a group of "retarded patients" being loaded into a train. Seeing Hitler at the window, the crowd became threatening. Mennecke apparently told this as an "anecdote" rather than something he knew to be true.</ref><ref>Lifton (1986): footnote 1</ref> Despite his private fury, Hitler knew that he could not afford a confrontation with the Church at a time when Germany was engaged in a life-and-death war, a belief which was reinforced by the advice of Goebbels, ], head of the Party Chancellery, and Heinrich Himmler, head of the SS. Robert Lifton writes: "Nazi leaders faced the prospect of either having to imprison prominent, highly admired clergymen and other protesters&nbsp;– a course with consequences in terms of adverse public reaction they greatly feared&nbsp;– or else end the programme." Himmler said: "If operation T4 had been entrusted to the SS, things would have happened differently", because "when the Führer entrusts us with a job, we know how to deal with it correctly, without causing useless uproar among the people."<ref>Lifton (1986): 95</ref>


Galen's sermons were not reported in the German press but were circulated illegally in leaflets. The text was dropped by the ] over German troops.{{sfn|Burleigh|2008|p=262}}{{sfn|Lifton|1986|p=94}} In 2009, ] wrote that "This was the strongest, most explicit and most widespread protest movement against any policy since the beginning of the Third Reich".{{sfn|Evans|2009|p=98}} Local Nazis asked for Galen to be arrested but Goebbels told Hitler that such action would provoke a revolt in Westphalia and Hitler decided to wait until after the war to take revenge.{{sfn|Kershaw|2000|pp=427, 429}}{{sfn|Burleigh|2008|p=262}}
On 24 August 1941 Hitler ordered the cancellation of the T4 programme. He issued strict instructions to the Gauleiters to avoid further provocations of the churches for the duration of the war. The invasion of the Soviet Union in June provided new opportunities to use the T4 personnel. Many were transferred to the east to begin work on a vastly greater programme of killing: the "] of the Jewish question". But the winding up of the T4 programme did not end the killing of people with disabilities. From the end of 1941, the killing became less systematic. Lifton documents that the killing of both adults and children continued to the end of the war, on the local initiative of institute directors and party leaders. The methods reverted to those employed before use of the gas chambers: lethal injection, or simple starvation.<ref>Lifton (1986): 96–102.</ref> Kershaw estimates that by the end of 1941 75,000 to 100,000 people had been killed in the T4 programme. Afterward tens of thousands of concentration camp inmates, and people judged incapable of work, were killed in Germany between 1942 and 1945. (This figure does not include the Jews who were deported to their deaths in 1942 and 1943). The Hartheim and Hardamar centres, for example, continued to kill people sent to them from all over Germany until 1945.

In 1986, Lifton wrote, "Nazi leaders faced the prospect of either having to imprison prominent, highly admired clergymen and other protesters – a course with consequences in terms of adverse public reaction they greatly feared – or else end the programme".{{sfn|Lifton|1986|p=95}} Evans considered it "at least possible, even indeed probable" that the T4 programme would have continued beyond Hitler's initial quota of 70,000 deaths but for the public reaction to Galen's sermon.{{sfn|Evans|2009|p=112}} Burleigh called assumptions that the sermon affected Hitler's decision to suspend the T4 programme "wishful thinking" and noted that the various Church hierarchies did not complain after the transfer of T4 personnel to {{lang|de|Aktion Reinhard}}.{{sfn|Burleigh|2008|p=26}} ] wrote that it was not the criticism from the Church but rather the loss of secrecy and "general popular disquiet about the way euthanasia was implemented" that caused the killings to be suspended.{{sfn|Friedlander|1997|p=111}}


Galen had detailed knowledge of the euthanasia programme by July 1940 but did not speak out until almost a year after Protestants had begun to protest. In 2002, Beth A. Griech-Polelle wrote:

Aktion T4 (German, pronounced [akˈtsi̯oːn teː fiːɐ]) was a campaign of mass murder by involuntary euthanasia which targeted people with disabilities in Nazi Germany. The term was first used in post-war trials against doctors who had been involved in the killings. The name T4 is an abbreviation of Tiergartenstraße 4, a street address of the Chancellery department set up in early 1940, in the Berlin borough of Tiergarten, which recruited and paid personnel associated with Aktion T4. Certain German physicians were authorised to select patients "deemed incurably sick, after most critical medical examination" and then administer to them a "mercy death" (Gnadentod). In October 1939, Adolf Hitler signed a "euthanasia note", backdated to 1 September 1939, which authorised his physician Karl Brandt and Reichsleiter Philipp Bouhler to begin the killing.

The killings took place from September 1939 until the end of the war in 1945; from 275,000 to 300,000 people were killed in psychiatric hospitals in Germany and Austria, occupied Poland and the Protectorate of Bohemia and Moravia (now the Czech Republic). The number of victims was originally recorded as 70,273 but this number has been increased by the discovery of victims listed in the archives of the former East Germany. About half of those killed were taken from church-run asylums, often with the approval of the Protestant or Catholic authorities of the institutions.

The Holy See announced on 2 December 1940 that the policy was contrary to divine law and that "the direct killing of an innocent person because of mental or physical defects is not allowed" but the declaration was not upheld by all Catholic authorities in Germany. In the summer of 1941, protests were led in Germany by the bishop of Münster, Clemens von Galen, whose intervention led to "the strongest, most explicit and most widespread protest movement against any policy since the beginning of the Third Reich", according to Richard J. Evans.

Several reasons have been suggested for the killings, including eugenics, racial hygiene, and saving money. Physicians in German and Austrian asylums continued many of the practices of Aktion T4 until the defeat of Germany in 1945, in spite of its official cessation in August 1941. The informal continuation of the policy led to 93,521 "beds emptied" by the end of 1941. Technology developed under Aktion T4, particularly the use of lethal gas on large numbers of people, was taken over by the medical division of the Reich Interior Ministry, along with the personnel of Aktion T4, who participated in mass murder of Jewish people. The programme was authorised by Hitler but the killings have since come to be viewed as murders in Germany. The number of people killed was about 200,000 in Germany and Austria, with about 100,000 victims in other European countries. Following the war, a number of the perpetrators were tried and convicted for murder and crimes against humanity.

Background

At the beginning of the twentieth century, the sterilisation of people carrying what were considered to be hereditary defects and in some cases those exhibiting what was thought to be hereditary "antisocial" behaviour, was a respectable field of medicine. Canada, Denmark, Switzerland and the US had passed laws enabling coerced sterilisation. Studies conducted in the 1920s ranked Germany as a country that was unusually reluctant to introduce sterilisation legislation. In his book Mein Kampf (1924), Hitler wrote that one day racial hygiene "will appear as a deed greater than the most victorious wars of our present bourgeois era".

In July 1933, the "Law for the Prevention of Hereditarily Diseased Offspring" prescribed compulsory sterilisation for people with conditions thought to be hereditary, such as schizophrenia, epilepsy, Huntington's chorea and "imbecility". Sterilisation was also legalised for chronic alcoholism and other forms of social deviance. The law was administered by the Interior Ministry under Wilhelm Frick through special Hereditary Health Courts (Erbgesundheitsgerichte), which examined the inmates of nursing homes, asylums, prisons, aged-care homes and special schools, to select those to be sterilised. It is estimated that 360,000 people were sterilised under this law between 1933 and 1939.

The policy and research agenda of racial hygiene and eugenics were promoted by Emil Kraepelin. The eugenic sterilisation of persons diagnosed with (and viewed as predisposed to) schizophrenia was advocated by Eugen Bleuler, who presumed racial deterioration because of "mental and physical cripples" in his Textbook of Psychiatry,

The more severely burdened should not propagate themselves... If we do nothing but make mental and physical cripples capable of propagating themselves, and the healthy stocks have to limit the number of their children because so much has to be done for the maintenance of others, if natural selection is generally suppressed, then unless we will get new measures our race must rapidly deteriorate.

Within the Nazi administration, the idea of including in the programme people with physical disabilities had to be expressed carefully, because the Reich Minister of Propaganda, Joseph Goebbels, had a deformed right leg. After 1937, the acute shortage of labour in Germany arising from rearmament, meant that anyone capable of work was deemed to be "useful", exempted from the law and the rate of sterilisation declined. The term Aktion T4 is a post-war coining; contemporary German terms included Euthanasie (euthanasia) and Gnadentod (merciful death). The T4 programme stemmed from the Nazi Party policy of "racial hygiene", a belief that the German people needed to be cleansed of racial enemies, which included anyone confined to a mental health facility and people with simple physical disabilities. New insulin shock treatments were used by German psychiatrists to find out if patients with schizophrenia were curable.

Implementation

NSDAP Reichsleiter Philipp Bouhler, head of the T4 programme

Karl Brandt, doctor to Hitler and Hans Lammers, the head of the Reich Chancellery, testified after the war that Hitler had told them as early as 1933—when the sterilisation law was passed—that he favoured the killing of the incurably ill but recognised that public opinion would not accept this. In 1935, Hitler told the Leader of Reich Doctors, Gerhard Wagner, that the question could not be taken up in peacetime; "Such a problem could be more smoothly and easily carried out in war". He wrote that he intended to "radically solve" the problem of the mental asylums in such an event. Aktion T4 began with a "trial" case in late 1938. Hitler instructed Brandt to evaluate a petition sent by two parents for the "mercy killing" of their son who was blind and had physical and developmental disabilities. The child, born near Leipzig and eventually identified as Gerhard Kretschmar, was killed in July 1939. Hitler instructed Brandt to proceed in the same manner in all similar cases.

On 18 August 1939, three weeks after the killing of the boy, the Reich Committee for the Scientific Registering of Hereditary and Congenital Illnesses was established to register sick children or newborns identified as defective. The secret killing of infants began in 1939 and increased after the war started; by 1941, more than 5,000 children had been killed. Hitler was in favour of killing those whom he judged to be lebensunwertes Leben ('Life unworthy of life'). A few months before the "euthanasia" decree, in a 1939 conference with Leonardo Conti, Reich Health Leader and State Secretary for Health in the Interior Ministry, and Hans Lammers, Chief of the Reich Chancellery, Hitler gave as examples the mentally ill who he said could only be "bedded on sawdust or sand" because they "perpetually dirtied themselves" and "put their own excrement into their mouths". This issue, according to the Nazi regime, assumed a new urgency in wartime.

After the invasion of Poland, Hermann Pfannmüller (Head of the State Hospital near Munich) said

It is unbearable to me that the flower of our youth must lose their lives at the front, so that that feeble-minded and asocial element can have a secure existence in the asylum.

Pfannmüller advocated killing by a gradual decrease of food, which he believed was more merciful than poison injections.

Karl Brandt, Hitler's personal doctor and organiser of Aktion T4

The German eugenics movement had an extreme wing even before the Nazis came to power. As early as 1920, Alfred Hoche and Karl Binding advocated killing people whose lives were "unworthy of life" (lebensunwertes Leben). Darwinism was interpreted by them as justification of the demand for "beneficial" genes and eradication of the "harmful" ones. Robert Lifton wrote, "The argument went that the best young men died in war, causing a loss to the Volk of the best genes. The genes of those who did not fight (the worst genes) then proliferated freely, accelerating biological and cultural degeneration". The advocacy of eugenics in Germany gained ground after 1930, when the Depression was used to excuse cuts in funding to state mental hospitals, creating squalor and overcrowding.

Many German eugenicists were nationalists and antisemites, who embraced the Nazi regime with enthusiasm. Many were appointed to positions in the Health Ministry and German research institutes. Their ideas were gradually adopted by the majority of the German medical profession, from which Jewish and communist doctors were soon purged. During the 1930s, the Nazi Party had carried out a campaign of propaganda in favour of euthanasia. The National Socialist Racial and Political Office (NSRPA) produced leaflets, posters and short films to be shown in cinemas, pointing out to Germans the cost of maintaining asylums for the incurably ill and insane. These films included The Inheritance (Das Erbe, 1935), The Victim of the Past (Opfer der Vergangenheit, 1937), which was given a major première in Berlin and was shown in all German cinemas, and I Accuse (Ich klage an, 1941) which was based on a novel by Hellmuth Unger, a consultant for "child euthanasia".

Killing of children

In mid-1939, Hitler authorised the creation of the Reich Committee for the Scientific Registering of Serious Hereditary and Congenital Illnesses (Reichsausschuss zur wissenschaftlichen Erfassung erb- und anlagebedingter schwerer Leiden) led by his physician, Karl Brandt, administered by Herbert Linden of the Interior Ministry, leader of German Red Cross Reichsarzt SS und Polizei Ernst-Robert Grawitz and SS-Oberführer Viktor Brack. Brandt and Bouhler were authorised to approve applications to kill children in relevant circumstances, though Bouhler left the details to subordinates such as Brack and SA-Oberführer Werner Blankenburg.

Extermination centres were established at six existing psychiatric hospitals: Bernburg, Brandenburg, Grafeneck, Hadamar, Hartheim, and Sonnenstein. One thousand children under the age of 17 were killed at the institutions Am Spiegelgrund and Gugging in Austria. They played a crucial role in developments leading to the Holocaust. As a related aspect of the "medical" and scientific basis of this programme, the Nazi doctors took thousands of brains from 'euthanasia' victims for research.

Viktor Brack, organiser of the T4 Programme

From August 1939, the Interior Ministry registered children with disabilities, requiring doctors and midwives to report all cases of newborns with severe disabilities; the 'guardian' consent element soon disappeared. Those to be killed were identified as "all children under three years of age in whom any of the following 'serious hereditary diseases' were 'suspected': idiocy and Down syndrome (especially when associated with blindness and deafness); microcephaly; hydrocephaly; malformations of all kinds, especially of limbs, head, and spinal column; and paralysis, including spastic conditions". The reports were assessed by a panel of medical experts, of whom three were required to give their approval before a child could be killed.

The Ministry used deceit when dealing with parents or guardians, particularly in Catholic areas, where parents were generally uncooperative. Parents were told that their children were being sent to "Special Sections", where they would receive improved treatment. The children sent to these centres were kept for "assessment" for a few weeks and then killed by injection of toxic chemicals, typically phenol; their deaths were recorded as "pneumonia". Autopsies were usually performed and brain samples were taken to be used for "medical research". Post mortem examinations apparently helped to ease the consciences of many of those involved, giving them the feeling that there was a genuine medical purpose to the killings. The most notorious of these institutions in Austria was Am Spiegelgrund, where from 1940 to 1945, 789 children were killed by lethal injection, gas poisoning and physical abuse. Children's brains were preserved in jars of formaldehyde and stored in the basement of the clinic and in the private collection of Heinrich Gross, one of the institution's directors, until 2001.

When the Second World War began in September 1939, less rigorous standards of assessment and a quicker approval process were adopted. Older children and adolescents were included and the conditions covered came to include

... various borderline or limited impairments in children of different ages, culminating in the killing of those designated as juvenile delinquents. Jewish children could be placed in the net primarily because they were Jewish; and at one of the institutions, a special department was set up for 'minor Jewish-Aryan half-breeds'.

— Lifton

More pressure was placed on parents to agree to their children being sent away. Many parents suspected what was happening and refused consent, especially when it became apparent that institutions for children with disabilities were being systematically cleared of their charges. The parents were warned that they could lose custody of all their children and if that did not suffice, the parents could be threatened with call-up for 'labour duty'. By 1941, more than 5,000 children had been killed. The last child to be killed under Aktion T4 was Richard Jenne on 29 May 1945, in the children's ward of the Kaufbeuren-Irsee state hospital in Bavaria, Germany, more than three weeks after US Army troops had occupied the town.

Killing of adults

Invasion of Poland

Brandt and Bouhler developed plans to expand the programme of euthanasia to adults. In July 1939 they held a meeting attended by Conti and Professor Werner Heyde, head of the SS medical department. This meeting agreed to arrange a national register of all institutionalised people with mental illnesses or physical disabilities. The first adults with disabilities to be killed en masse by the Nazi regime were Poles. After the invasion on 1 September 1939, adults with disabilities were shot by the SS men of Einsatzkommando 16, Selbstschutz and EK-Einmann under the command of SS-Sturmbannführer Rudolf Tröger, overseen by Reinhard Heydrich, during Operation Tannenberg.

All hospitals and mental asylums of the Wartheland were emptied. The region was incorporated into Germany and earmarked for resettlement by Volksdeutsche following the German conquest of Poland. In the Danzig (now Gdańsk) area, some 7,000 Polish patients of various institutions were shot and 10,000 were killed in the Gdynia area. Similar measures were taken in other areas of Poland destined for incorporation into Germany. The first experiments with the gassing of patients were conducted in October 1939 at Fort VII in Posen (occupied Poznań), where hundreds of prisoners were killed by means of carbon monoxide poisoning, in an improvised gas chamber developed by Albert Widmann, chief chemist of the German Criminal Police (Kripo). In December 1939, Reichsführer-SS Heinrich Himmler witnessed one of these gassings, ensuring that this invention would later be put to much wider uses.

The idea of killing adult mental patients soon spread from occupied Poland to adjoining areas of Germany, probably because Nazi Party and SS officers in these areas were most familiar with what was happening in Poland. These were also the areas where Germans wounded from the Polish campaign were expected to be accommodated, which created a demand for hospital space. The Gauleiter of Pomerania, Franz Schwede-Coburg, sent 1,400 patients from five Pomeranian hospitals to undisclosed locations in occupied Poland, where they were shot. The Gauleiter of East Prussia, Erich Koch, had 1,600 patients killed out of sight. More than 8,000 Germans were killed in this initial wave of killings carried out on the orders of local officials, although Himmler certainly knew and approved of them.

The legal basis for the programme was a 1939 letter from Hitler, not a formal "Führer's decree" with the force of law. Hitler bypassed Conti, the Health Minister and his department, who might have raised questions about the legality of the programme and entrusted it to Bouhler and Brandt.

Reich Leader Bouhler and Dr. Brandt are entrusted with the responsibility of extending the authority of physicians, to be designated by name, so that patients who, after a most critical diagnosis, on the basis of human judgment , are considered incurable, can be granted mercy death .

— Adolf Hitler, 1 September 1939

The killings were administered by Viktor Brack and his staff from Tiergartenstraße 4, disguised as the "Charitable Foundation for Cure and Institutional Care" offices which served as the front and was supervised by Bouhler and Brandt. The officials in charge included Herbert Linden, who had been involved in the child killing programme; Ernst-Robert Grawitz, chief physician of the SS and August Becker, an SS chemist. The officials selected the doctors who were to carry out the operational part of the programme; based on political reliability as long-term Nazis, professional reputation and sympathy for radical eugenics. The list included physicians who had proved their worth in the child-killing programme, such as Unger, Heinze and Hermann Pfannmüller. The recruits were mostly psychiatrists, notably Professor Carl Schneider of Heidelberg, Professor Max de Crinis of Berlin and Professor Paul Nitsche from the Sonnenstein state institution. Heyde became the operational leader of the programme, succeeded later by Nitsche.

Listing of targets from hospital records

Hartheim Euthanasia Centre, where over 18,000 people were killed

In early October, all hospitals, nursing homes, old-age homes and sanatoria were required to report all patients who had been institutionalised for five years or more, who had been committed as "criminally insane", who were of "non-Aryan race" or who had been diagnosed with any on a list of conditions. The conditions included schizophrenia, epilepsy, Huntington's chorea, advanced syphilis, senile dementia, paralysis, encephalitis and "terminal neurological conditions generally". Many doctors and administrators assumed that the reports were to identify inmates who were capable of being drafted for "labour service" and tended to overstate the degree of incapacity of their patients, to protect them from labour conscription. When some institutions refused to co-operate, teams of T4 doctors (or Nazi medical students) visited and compiled the lists, sometimes in a haphazard and ideologically motivated way. During 1940, all Jewish patients were removed from institutions and killed.

As with child inmates, adults were assessed by a panel of experts, working at the Tiergartenstraße offices. The experts were required to make their judgements on the reports, not medical histories or examinations. Sometimes they dealt with hundreds of reports at a time. On each they marked a + (death), a - (life), or occasionally a ? meaning that they were unable to decide. Three "death" verdicts condemned the person and as with reviews of children, the process became less rigorous, the range of conditions considered "unsustainable" grew broader and zealous Nazis further down the chain of command increasingly made decisions on their own initiative.

Gassing

The first gassings in Germany proper took place in January 1940 at the Brandenburg Euthanasia Centre. The operation was headed by Brack, who said "the needle belongs in the hand of the doctor". Bottled pure carbon monoxide gas was used. At trials, Brandt described the process as a "major advance in medical history". Once the efficacy of the method was confirmed, it became standard and was instituted at a number of centres in Germany under the supervision of Widmann, Becker and Christian Wirth – a Kripo officer who later played a prominent role in the Final Solution (extermination of Jews) as commandant of newly built death camps in occupied Poland. In addition to Brandenburg, the killing centres included Grafeneck Castle in Baden-Württemberg (10,824 dead), Schloss Hartheim near Linz in Austria (over 18,000 dead), Sonnenstein in Saxony (15,000 dead), Bernburg in Saxony-Anhalt and Hadamar in Hesse (14,494 dead). The same facilities were also used to kill mentally sound prisoners transferred from concentration camps in Germany, Austria and occupied parts of Poland.

Bishop Jan Maria Michał Kowalski, killed at Hartheim

Condemned patients were transferred from their institutions to new centres in T4 Charitable Ambulance buses, called the Community Patients Transports Service. They were run by teams of SS men wearing white coats, to give it an air of medical care. To prevent the families and doctors of the patients from tracing them, the patients were often first sent to transit centres in major hospitals, where they were supposedly assessed. They were moved again to special treatment (Sonderbehandlung) centres. Families were sent letters explaining that owing to wartime regulations, it was not possible for them to visit relatives in these centres. Most of these patients were killed within 24 hours of arriving at the centres and their bodies cremated. Some bodies were dissected for medical research whilst others had their gold teeth extracted. For every person killed, a death certificate was prepared, giving a false but plausible cause of death. This was sent to the family along with an urn of ashes (random ashes, since the victims were cremated en masse). The preparation of thousands of falsified death certificates took up most of the working day of the doctors who operated the centres.

During 1940, the centres at Brandenburg, Grafeneck and Hartheim killed nearly 10,000 people each, while another 6,000 were killed at Sonnenstein. In all, about 35,000 people were killed in T4 operations that year. Operations at Brandenburg and Grafeneck were wound up at the end of the year, partly because the areas they served had been cleared and partly because of public opposition. In 1941, however, the centres at Bernburg and Sonnenstein increased their operations, while Hartheim (where Wirth and Franz Stangl were successively commandants) continued as before. Another 35,000 people were killed before August 1941, when the T4 programme was officially shut down by Hitler. Even after that date the centres continued to be used to kill concentration camp inmates: eventually some 20,000 people in this category were killed.

In 1971, Gitta Sereny conducted interviews with Stangl, who was in prison in Düsseldorf, having been convicted of co-responsibility for killing 900,000 people, while commandant of the Sobibor and Treblinka extermination camps in Poland. Stangl gave Sereny a detailed account of the operations of the T4 programme based on his time as commandant of the killing facility at the Hartheim institute. He described how the inmates of various asylums were removed and transported by bus to Hartheim. Some were in no mental state to know what was happening to them but many were perfectly sane and for them various forms of deception were used. They were told they were at a special clinic where they would receive improved treatment and were given a brief medical examination on arrival. They were induced to enter what appeared to be a shower block, where they were gassed with carbon monoxide (the ruse was also used at extermination camps). Some of the victims knew their fate and tried to defend themselves.

Number of euthanasia victims

The SS functionaries and hospital staff associated with Aktion T4 in the German Reich were paid from the central office at Tiergartenstraße 4 in Berlin from the spring of 1940. The SS and police from SS-Sonderkommando Lange responsible for murdering the majority of patients in the annexed territories of Poland since October 1939, took their salaries from the normal police fund, supervised by the administration of the newly formed Wartheland district; the programme in Germany and occupied Poland was overseen by Heinrich Himmler. Before 2013, it was believed that 70,000 persons were murdered in the euthanasia programme, but the German Federal Archives reported that research in the archives of former East Germany indicated that the number of victims in Germany and Austria from 1939 to 1945 was about 200,000 persons and that another 100,000 persons were victims in other European countries. In the German T4 centres there was at least the semblance of legality in keeping records and writing letters. In Polish psychiatric hospitals no one was left behind. Killings were inflicted using gas-vans, sealed army bunkers and machine guns; families were not informed about the murdered relatives and the empty wards were handed over to the SS.

Technology and personnel transfer to death camps

See also: Category:Aktion T4 personnel and T4-Gutachter

After the official end of the euthanasia programme in 1941, most of the personnel and high-ranking officials, as well as gassing technology and the techniques used to deceive victims, were transferred under the jurisdiction of the national medical division of the Reich Interior Ministry. Further gassing experiments with the use of mobile gas chambers (Einsatzwagen) were conducted at Soldau concentration camp by Herbert Lange following Operation Barbarossa. Lange was appointed commander of the Chełmno extermination camp in December 1941. He was given three gas vans by the Reich Security Main Office (RSHA), converted by the Gaubschat GmbH in Berlin and before February 1942, killed 3,830 Polish Jews and around 4,000 Romani, under the guise of "resettlement". After the Wannsee conference, implementation of gassing technology was accelerated by Heydrich. Beginning in the spring of 1942, three killing factories were built secretly in east-central Poland. The SS officers responsible for the earlier Aktion T4, including Wirth, Stangl and Irmfried Eberl, had important roles in the implementation of the "Final Solution" for the next two years. The first killing centre, equipped with stationary gas chambers, modelled on technology developed under Aktion T4, was established at Bełżec in the General Government territory of occupied Poland; the decision preceded the Wannsee Conference of January 1942 by three months.

Opposition

Gas chamber at Hadamar

In January 1939, Brack commissioned a paper from Professor of Moral Theology at the University of Paderborn, Joseph Mayer, on the likely reactions of the churches in the event of a state euthanasia programme being instituted. Mayer – a longstanding euthanasia advocate – reported that the churches would not oppose such a programme if it was seen to be in the national interest. Brack showed this paper to Hitler in July and it may have increased his confidence that the "euthanasia" programme would be acceptable to German public opinion. Notably, when Sereny interviewed Mayer shortly before his death in 1967, he denied that he formally condoned the killing of people with disabilities but no copies of this paper are known to survive.

Some bureaucrats opposed the T4 programme; Lothar Kreyssig, a district judge and member of the Confessing Church, wrote to Justice Minister Franz Gürtner protesting that the action was illegal since no law or formal decree from Hitler had authorised it. Gürtner replied, "If you cannot recognise the will of the Führer as a source of law, then you cannot remain a judge" and had Kreyssig dismissed. Hitler had a policy of not issuing written instructions for matters which could later be condemned by the international community but made an exception when he provided Bouhler and Brack with written authority for the T4 programme. Hitler wrote a confidential letter in October 1939 to overcome opposition within the German state bureaucracy. Hitler told Bouhler that, "the Führer's Chancellery must under no circumstances be seen to be active in this matter". Gürtner had to be shown Hitler's letter in August 1940 to gain his co-operation.

Exposure

In the towns where the killing centres were located, some people saw the inmates arrive in buses, saw smoke from the crematoria chimneys and noticed that the buses were returning empty. In Hadamar, ashes containing human hair rained down on the town and despite the strictest orders, some of the staff at the killing centres talked about what was going on. In some cases families could tell that the causes of death in certificates were false, e.g. when a patient was claimed to have died of appendicitis, even though his appendix had been removed some years earlier. In other cases, families in the same town would receive death certificates on the same day. In May 1941, the Frankfurt County Court wrote to Gürtner describing scenes in Hadamar, where children shouted in the streets that people were being taken away in buses to be gassed.

Hans Gerhard Creutzfeldt in 1920

During 1940, rumours of what was taking place spread and many Germans withdrew their relatives from asylums and sanatoria to care for them at home, often with great expense and difficulty. In some places doctors and psychiatrists co-operated with families to have patients discharged or if the families could afford it, transferred them to private clinics beyond the reach of T4. Other doctors "re-diagnosed" patients so that they no longer met the T4 criteria, which risked exposure when Nazi zealots from Berlin conducted inspections. In Kiel, Professor Hans Gerhard Creutzfeldt managed to save nearly all of his patients. Lifton listed a handful of psychiatrists and administrators who opposed the killings; many doctors collaborated, either through ignorance, agreement with Nazi eugenicist policies or fear of the regime.

Protest letters were sent to the Reich Chancellery and the Ministry of Justice, some from Nazi Party members. The first open protest against the removal of people from asylums took place at Absberg in Franconia in February 1941 and others followed. The SD report on the incident at Absberg noted that "the removal of residents from the Ottilien Home has caused a great deal of unpleasantness" and described large crowds of Catholic townspeople, among them Party members, protesting against the action. Similar petitions and protests occurred throughout Austria as rumours spread of mass killings at the Hartheim Euthanasia Centre and of mysterious deaths at the children's clinic, Am Spiegelgrund in Vienna. Anna Wödl, a nurse and mother of a child with a disability, vehemently petitioned to Hermann Linden at the Reich Ministry of the Interior in Berlin to prevent her son, Alfred, from being transferred from Gugging, where he lived and which also became a euthanasia center. Wödl failed and Alfred was sent to Am Spiegelgrund, where he was killed on 22 February 1941. His brain was preserved in formaldehyde for "research" and stored in the clinic for sixty years.

Church protests

Main article: Nazi euthanasia and the Catholic Church

The Lutheran theologian Friedrich von Bodelschwingh (director of the Bethel Institution for Epilepsy at Bielefeld) and Pastor Paul-Gerhard Braune (director of the Hoffnungstal Institution near Berlin) protested. Bodelschwingh negotiated directly with Brandt and indirectly with Hermann Göring, whose cousin was a prominent psychiatrist. Braune had meetings with Gürtner, who was always dubious about the legality of the programme. Gürtner later wrote a strongly worded letter to Hitler protesting against it; Hitler did not read it but was told about it by Lammers. Bishop Theophil Wurm, presiding over the Evangelical-Lutheran Church in Württemberg, wrote to Interior Minister Frick in March 1940 and that month a confidential report from the Sicherheitsdienst (SD) in Austria, warned that the killing programme must be implemented with stealth "...to avoid a probable backlash of public opinion during the war". On 4 December 1940, Reinhold Sautter, the Supreme Church Councillor of the Württemberg State Church, complained to the Nazi Ministerial Councillor Eugen Stähle against the murders in Grafeneck Castle. Stähle said "The fifth commandment Thou shalt not kill, is no commandment of God but a Jewish invention".

Bishop Heinrich Wienken of Berlin, a leading member of the Caritas Association, was selected by the Fulda episcopal synod to represent the views of the Catholic Church in meetings with T4 operatives. In 2008, Michael Burleigh wrote

Clemens von Galen

Wienken seems to have gone partially native in the sense that he gradually abandoned an absolute stance based on the Fifth Commandment in favour of winning limited concessions regarding the restriction of killing to 'complete idiots', access to the sacraments and the exclusion of ill Roman Catholic priests from these policies.

Despite a decree issued by the Vatican on 2 December 1940 stating that the T4 policy was "against natural and positive Divine law" and that "The direct killing of an innocent person because of mental or physical defects is not allowed", the Catholic Church hierarchy in Germany decided to take no further action. Incensed by the Nazi appropriation of Church property in Münster to accommodate people made homeless by an air raid, in July and August 1941, the bishop of Münster, Clemens August Graf von Galen, gave four sermons criticising the Nazis for arresting Jesuits, confiscating church property and for the euthanasia program. Galen sent the text to Hitler by telegram, calling on

... the Führer to defend the people against the Gestapo. It is a terrible, unjust and catastrophic thing when man opposes his will to the will of God ... We are talking about men and women, our compatriots, our brothers and sisters. Poor unproductive people if you wish, but does this mean that they have lost their right to live?

Galen's sermons were not reported in the German press but were circulated illegally in leaflets. The text was dropped by the Royal Air Force over German troops. In 2009, Richard J. Evans wrote that "This was the strongest, most explicit and most widespread protest movement against any policy since the beginning of the Third Reich". Local Nazis asked for Galen to be arrested but Goebbels told Hitler that such action would provoke a revolt in Westphalia and Hitler decided to wait until after the war to take revenge.

A plaque set in the pavement at No 4 Tiergartenstraße commemorates the victims of the Nazi euthanasia programme.

In 1986, Lifton wrote, "Nazi leaders faced the prospect of either having to imprison prominent, highly admired clergymen and other protesters – a course with consequences in terms of adverse public reaction they greatly feared – or else end the programme". Evans considered it "at least possible, even indeed probable" that the T4 programme would have continued beyond Hitler's initial quota of 70,000 deaths but for the public reaction to Galen's sermon. Burleigh called assumptions that the sermon affected Hitler's decision to suspend the T4 programme "wishful thinking" and noted that the various Church hierarchies did not complain after the transfer of T4 personnel to Aktion Reinhard. Henry Friedlander wrote that it was not the criticism from the Church but rather the loss of secrecy and "general popular disquiet about the way euthanasia was implemented" that caused the killings to be suspended.

Galen had detailed knowledge of the euthanasia programme by July 1940 but did not speak out until almost a year after Protestants had begun to protest. In 2002, Beth A. Griech-Polelle wrote:

Worried lest they be classified as outsiders or internal enemies, they waited for Protestants, that is the "true Germans", to risk a confrontation with the government first. If the Protestants were able to be critical of a Nazi policy, then Catholics could function as "good" Germans and yet be critical too.

On 29 June 1943, Pope Pius XII issued the encyclical Mystici corporis Christi, in which he condemned the fact that "physically deformed people, mentally disturbed people and hereditarily ill people have at times been robbed of their lives" in Germany. Following this, in September 1943, a bold but ineffectual condemnation was read by bishops from pulpits across Germany, denouncing the killing of "the innocent and defenceless mentally handicapped and mentally ill, the incurably infirm and fatally wounded, innocent hostages and disarmed prisoners of war and criminal offenders, people of a foreign race or descent".

Suspension and continuity

Commemorative plaque on wall on bunker No. 17 in Fort VII

On 24 August 1941, Hitler ordered the suspension of the T4 killings. After the invasion of the Soviet Union in June, many T4 personnel were transferred to the eastern front. The projected death total for the T4 programme of 70,000 deaths had been reached by August 1941. The termination of the T4 programme did not end the killing of people with disabilities; from the end of 1941, on the initiative of institute directors and local party leaders, the killing of adults and children continued, albeit less systematically, until the end of the war. After the bombing of Hamburg in July 1943, occupants of old age homes were killed. In the post-war trial of Dr. Hilda Wernicke, Berlin, August 1946, testimony was given that "500 old, broken women" who had survived the bombing of Stettin in June 1944 were euthanised at the Meseritz-Oberwalde Asylum. The Hartheim, Bernberg, Sonnenstein and Hadamar centres continued in use as "wild euthanasia" centres to kill people sent from all over Germany, until 1945. The methods were lethal injection or starvation, those employed before use of gas chambers. By the end of 1941, about 100,000 people had been killed in the T4 programme. From mid-1941, concentration camp prisoners too feeble or too much trouble to keep alive were murdered after a cursory psychiatric examination under Action 14f13.

Post-war

Doctors' trial

Main articles: Euthanasia trials and Doctors' trial

After the war trials were held in connection with the Nazi euthanasia programme at various places including Dresden, Frankfurt, Graz, Nuremberg and Tübingen. In December 1946 an American military tribunal (commonly called the Doctors' trial) prosecuted 23 doctors and administrators for their roles in war crimes and crimes against humanity. These crimes included the systematic killing of those deemed "unworthy of life", including people with mental disabilities, the people who were institutionalised mentally ill and people with physical impairments. After 140 days of proceedings, including the testimony of 85 witnesses and the submission of 1,500 documents, in August 1947 the court pronounced 16 of the defendants guilty. Seven were sentenced to death; the men, including Brandt and Brack, were executed on 2 June 1948.

The indictment read in part:

14. Between September 1939 and April 1945 the defendants Karl Brandt, Blome, Brack, and Hoven unlawfully, wilfully, and knowingly committed crimes against humanity, as defined by Article II of Control Council Law No. 10, in that they were principals in, accessories to, ordered, abetted, took a consenting part in, and were connected with plans and enterprises involving the execution of the so called "euthanasia" program of the German Reich, in the course of which the defendants herein murdered hundreds of thousands of human beings, including German civilians, as well as civilians of other nations. The particulars concerning such murders are set forth in paragraph 9 of count two of this indictment and are incorporated herein by reference.

— International Military Tribunal

Earlier, in 1945, American forces tried seven staff members of the Hadamar killing centre for the killing of Soviet and Polish nationals, which was within their jurisdiction under international law, as these were the citizens of wartime allies. (Hadamar was within the American Zone of Occupation in Germany. This was before the Allied resolution of December 1945, to prosecute individuals for "crimes against humanity" for such mass atrocities.) Alfons Klein, Heinrich Ruoff and Karl Willig were sentenced to death and executed; the other four were given long prison sentences. In 1946, reconstructed German courts tried members of the Hadamar staff for the murders of nearly 15,000 German citizens. The chief physician, Adolf Wahlmann and Irmgard Huber, the head nurse, were convicted.

Memorials

The German national memorial to the people with disabilities murdered by the Nazis was dedicated in 2014 in Berlin. It is located in the pavement of a site next to the Tiergarten park, the location of the former villa at Tiergartenstraße 4 in Berlin, where more than 60 Nazi bureaucrats and doctors worked in secret under the "T4" programme to organise the mass murder of sanatorium and psychiatric hospital patients deemed unworthy to live.

Notes

  1. As many as 100,000 people may have been killed directly as part of Aktion T-4. Mass euthanasia killings were also carried out in the Eastern European countries and territories Nazi Germany conquered during the war. Categories are fluid and no definitive figure can be assigned but historians put the total number of victims at around 300,000.
  2. Tiergartenstraße 4 was the location of the Central Office and administrative headquarters of the Gemeinnützige Stiftung für Heil- und Anstalts- pflege (Charitable Foundation for Curative and Institutional Care).
  3. Notes on patient records from the archive "R 179" of the Chancellery of the Führer Main Office II b. Between 1939 and 1945, about 200,000 women, men and children in psychiatric institutions of the German Reich were killed in covert actions by gas, medication or starvation. Original: Zwischen 1939 und 1945 wurden ca. 200.000 Frauen, Männer und Kinder aus psychiatrischen Einrichtungen des Deutschen Reichs im mehreren verdeckten Aktionen durch Vergasung, Medikamente oder unzureichende Ernährung ermordet.
  4. Robert Lifton and Michael Burleigh estimated that twice the official number of T4 victims may have perished before the end of the war. Ryan and Schurman gave an estimated range of 200,000 and 250,000 victims of the policy upon the arrival of Allied troops in Germany.
  5. This was the result either of club foot or osteomyelitis. Goebbels is commonly said to have had club foot (talipes equinovarus), a congenital condition. William L. Shirer, who worked in Berlin as a journalist in the 1930s and was acquainted with Goebbels, wrote in The Rise and Fall of the Third Reich (1960) that the deformity was from a childhood attack of osteomyelitis and a failed operation to correct it.
  6. Robert Lifton wrote that this request was "encouraged"; the severely disabled child and the agreement of the parents to his killing were apparently genuine.
  7. Professors Werner Catel (a Leipzig psychiatrist) and Hans Heinze, head of a state institution for children with intellectual disabilities at Görden near Brandenburg; Ernst Wentzler a Berlin paediatric psychiatrist and the author Dr. Helmut Unger.
  8. Lifton concurs with this figure, but notes that the killing of children continued after the T4 programme was formally ended in 1941.
  9. The second phase of Operation Tannenberg referred to as the Unternehmen Tannenberg by Heydrich's Sonderreferat{ began in late 1939 under the codename Intelligenzaktion and lasted until January 1940, in which 36,000–42,000 people, including Polish children, were killed in Pomerania before the end of 1939.
  10. Several drafts of a formal euthanasia law were prepared but Hitler refused to authorise them. The senior participants in the programme always knew that it was not a law, even by the loose definition of legality prevailing in Nazi Germany.
  11. According to Lifton, most Jewish inmates of German mental institutions were dispatched to Lublin in Poland in 1940 and killed there.
  12. These figures come from the article Aktion T4 on the German Misplaced Pages, which cites Ernst Klee.
  13. Role of T4 "Inspector" Christian Wirth in the Holocaust.
