This New York Times-bestselling biography of the founder of computer science, with a new preface by the author that addresses Turing's royal pardon in 2013, is the definitive account of an extraordinary mind and life. In 1954, aged 41, Alan Turing took his own life.A NEW YORK TIMES BESTSELLER The official book behind the Academy Award-winning film The Imitation Game, starring Benedict Cumberbatch and Keira Knightley It is only a slight exaggeration to say that the British mathematician Alan Turing (1912-1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades-all before his suicide at age forty-one.

However, in 1952 his homosexuality rendered him a criminal and he was subjected to humiliating treatment. Turing's far-sighted plans for the digital era forged ahead into a vision for Artificial Intelligence. 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. But his vision went far beyond this achievement. He then headed the penetration of the super-secure U-boat communications. In 1940 his machines were breaking the Enigma-enciphered messages of Nazi Germany's air force.

Taken on by British Intelligence in 1938, as a shy young Cambridge don, he combined brilliant logic with a flair for engineering.
