The official book behind the Academy Award-winning film The Imitation Game,
starring Benedict Cumberbatch and Keira Knightley Alan Turing was the mathematician whose cipher-cracking transformed the Second
World War. Taken on by British Intelligence in 1938, as a shy young Cambridge
don, he combined brilliant logic with a flair for engineering. In 1940 his
machines were breaking the Enigma-enciphered messages of Nazi Germany's air
force. He then headed the penetration of the super-secure U-boat communications. But his vision went far beyond this achievement. Before the war he had invented
the concept of the universal machine, and in 1945 he turned this into the first
design for a digital computer. Turing's far-sighted plans for the digital era forged ahead into a vision for
Artificial Intelligence. However, in 1952 his homosexuality rendered him a
criminal and he was subjected to humiliating treatment. In 1954, aged 41, Alan
Turing took his own life.
