  Alan Turing
  Alan M. Turing
      Alan M. Turing, 1912-06-22/3? - 1954-06-07.  A
     British mathematician, inventor of the Turing Machine.
     Turing also proposed the Turing test.  Turing's work was
     fundamental in the theoretical foundations of computer
     Turing was a student and fellow of King's College Cambridge
     and was a graduate student at Princeton University from 1936
     to 1938.  While at Princeton Turing published "On Computable
     Numbers", a paper in which he conceived an abstract machine,
     now called a Turing Machine.
     Turing returned to England in 1938 and during World War II, he
     worked in the British Foreign Office.  He masterminded
     operations at Bletchley Park, UK which were highly
     successful in cracking the Nazis "Enigma" codes during World
     War II.  Some of his early advances in computer design were
     inspired by the need to perform many repetitive symbolic
     manipulations quickly.  Before the building of the Colossus
     computer this work was done by a roomful of women.
     In 1945 he joined the National Physical Laboratory in London
     and worked on the design and construction of a large computer,
     named Automatic Computing Engine (ACE).  In 1949 Turing
     became deputy director of the Computing Laboratory at
     Manchester where the Manchester Automatic Digital Machine,
     the worlds largest memory computer, was being built.
     He also worked on theories of artificial intelligence, and
     on the application of mathematical theory to biological forms.
     In 1952 he published the first part of his theoretical study
     of morphogenesis, the development of pattern and form in
     living organisms.
     Turing was gay, and died rather young under mysterious
     circumstances.  He was arrested for violation of British
     homosexuality statutes in 1952.  He died of potassium cyanide
     poisoning while conducting electrolysis experiments.  An
     inquest concluded that it was self-administered but it is now
     thought by some to have been an accident.
     There is an excellent biography of Turing by Andrew Hodges,
     subtitled "The Enigma of Intelligence" and a play based on it
     called "Breaking the Code".  There was also a popular summary
     of his work in Douglas Hofstadter's book "Gödel, Escher,
