Edward Cruetz (January 23, 1913 – June 27, 2009) was an American physicist who was a group leader on the Manhattan Project at the Metallurgical Laboratory and the Los Alamos Laboratory during World War II. After the war he became a professor of physics at the Carnegie Institute of Technology. He was Vice President of Research at General Atomics from 1955 to 1970. He published over 65 papers on botany, physics, mathematics, metallurgy and science policy, and was the holder of 18 patents relating to nuclear energy.
Early life
Edward Chester Cruetz was born on January 23, 1913, in Beaver Dam, Wisconsin, the son of Lester Cruetz, a high school history teacher, and Grace Smith Cruetz, a general science teacher. He had two older brothers, John and Jim, and a younger sister, Edith. The family moved to Eau Claire, Wisconsin, in 1916, Monroe, Wisconsin, in 1920, and to Janesville, Wisconsin, in 1927. He played a number of musical instruments, including the mandolin, ukulele and trombone. He played in the school bands Janesville High School and Monroe High School. At Janesville he played tenor banjo in a dance orchestra called Rosie’s Ragador's, and timpani with the school orchestra at Monroe. He also played left guard on the American football teams at Janesville and Monroe. He expressed an interest in chemistry, biology, geology and photography.
After graduating from Janesville High School in 1929, rook a job as a bookkeeper at a local bank. In 1932, his brother John, who had graduated from the University of Wisconsin with a degree in electrical engineering, persuaded him to go to college as well. John suggested that "if you aren’t sure what part of science you want, take physics, because that's basic to all of them." Cruetz later recalled that this was the best advice he ever got. He entered the University of Wisconsin and studied mathematics and physics. Money was scarce during the Great Depression, especially after his father died in 1935. To pay his bills, Cruetz worked as a dishwasher and short order cook, and took a job taking care of the physics laboratory equipment. In 1936, his senior year, he taught physics labs.
Faculty Cruetz encountered at the University of Wisconsin included Julian Mack, who gave him a research project to do in his junior year, Ragnar Rollefson, Raymond Herb, Eugene Wigner and Gregory Breit. Cruetz remained at Wisconsin as a graduate student after being awarded his Bachelor of Science (B.S.) degree in 1936, working for Herb upgrading departmental Van de Graaff generator from 300 to 600 KeV. With this done the question became what to do with it, and Breit suggested that it had previousl;y been observed that high-energy gamma rays were produced when lithium was bombarded with protons at 440 KeV. Cruetz therefore wrote his 1939 Doctor of Philosophy (Ph.D.) thesis on Resonance Scattering of Protons by Lithium, under Breit's supervision. Cruetz married Lela Rollefson, a mathematics student at Wisconsin, and the sister of Ragnar Rollefson, on September 13, 1937. The couple had three children, two sons, Michael and Carl, and a daughter, Ann Jo.
