Who was he???
Alan Mathison Turing was a British mathematician, logician, cryptanalyst, and computer scientist. He was born in 23 June 1912 and died in 7 June 1954, after possibly committing suicide although this may not be true (see article below). He made five major advances in the field of cryptanalysis at Bletchley Park, the GCCS wartime station, including specifying the bombe, an electromechanical device used to help decipher German Enigma encrypted signals. He also wrote two papers about mathematical approaches to code-breaking. He was arrested for homosexuality in 1952.
