A biography of the English mathematician Alan Turing, who was one of the inventors of the digital computer and one of the key figures in the breaking of the Enigma code, used by the Germans to send secret orders to their U-boats in World War II. Turing was also a homosexual in Britain at a time when this was illegal, besides being a security risk.
Alan Turing: the Enigma (Andrew Hodges) 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. This classic biography of the founder of computer science is the definitive account of an extraordinary mind and life.
