Alan Turing (1912 – 1954) - Turing is considered to be the father of theoretical computer science and artificial intelligence. During the Second World War, he worked at Bletchley Park, Britain's codebreaking centre. His work shortened the war in Europe by more than two years. Here seen in 1951.
It is hard to overstate the importance of Alan Turing, the British mathematician who died in 1954. He was a hero in science, for one. Turing invented the concepts that underlie modern computers and artificial intelligence. And he was a hero in war: He was a vital part of the British cryptographic team at Bletchley Park that cracked the German Enigma code during World War II.
Young Alan Turing (age 16) - founder of computer science, helped win World War II by decrypting the german coding machine Enigma. After the war he was tried in court for being gay, found guilty, forced to take castration pills, and then driven to commit suicide.
