Alan Turing  Born: June 23, 1912  Died: June 7, 1954  Briefly British mathematician, logician, and cryptographer. Since 1966, the Turing Award has been given annually by the Association for Computing Machinery to a person for technical contributions to the field of computing science. 
Alan Turing was a mathematician who in 1937 suggested a theoretical machine, since called a Turing Machine, that became the basis of modern computing. In 1950 he suggested what has become known as a "Turings test," still the criterion for recognizing intelligence in a machine. During World War II Turing led the team that succeeded in breaking German highlevel secret codes, using the first practical programmed computer, called Colossus. Turing was a homosexual, a crime in England at the time, and in 1952 he was tried, convicted and sentenced to estrogen treatments. In 1954 he died of cyanide poisoning, an apparent suicide.
