Alan Turing: The Enigma
The definitive life of the man who broke the U-boat Enigma and conceived the computer — then was destroyed by the country he saved.
The Verdict
The definitive life of the man who helped break the U-boat Enigma and imagined the computer — then was destroyed by the country he saved. Andrew Hodges, himself a mathematician, writes Turing's story with rare authority on both the codebreaking at Bletchley and the mathematics that would reshape the world, and with deep sympathy for the persecution that followed: prosecuted for his homosexuality, subjected to chemical treatment, dead at forty-one. It is the biography behind The Imitation Game, and far richer and truer than the film. A great life, and a national shame.
