George Spencer-Brown is described in (the source for this entry) as a "mathematician, consulting engineer, psychologist, educational consultant and practitioner, consulting psychotherapist, author, and poet". He is best known for his 1969 book Laws of Form. The calculus presented in that book has influenced, among others, Heinz von Foerster, Louis Kauffman, Niklas Luhmann, and Francisco Varela).
Born on April 2, 1923 in Grimsby, Lincolnshire, England, Spencer-Brown obtained an M.B. from London Hospital Medical College (1940). After serving in the Royal Navy (1943-47), he studied at Trinity College, Cambridge, earning Honours in Philosophy (1950) and Psychology (1951). From 1952 to 1958, he taught philosophy at Christ Church College, Oxford, earning M.A. degrees in 1954 from both Oxford and Cambridge, and writing his 1957 book "Probability and Scientific Inference". During the 1960s, he became a disciple of the radical British psychiatrist R.D. Laing, frequently cited in "Laws of Form".
"Laws of Form" emerged out of work in electronic engineering Spencer-Brown did around 1960, and from lectures on mathematical logic he later gave under the auspices of the University of London's extension program. From 1969 onward he was a Member of the Department of Pure Mathematics and Mathematical Statistics of the University of Cambridge. In the 1970s and 1980s he was visiting professor at the University of Western Australia, Stanford University and at the University of Maryland, College Park. In a 1976 letter to the Editor of Nature , Spencer-Brown claimed a noncomputational proof of the four-colour theorem. Mathematicians who have examined this proof reject its validity.
