Alan Turing was an extraordinary man who crammed into his 42 years the careers of mathematician, codebreaker, computer scientist and biologist. He is widely regarded as a war hero grossly mistreated by his unappreciative country, and it has become hard to disentangle the real man from the story. It is easy to cast him as a misfit, the stereotypical professor. But actually Alan Turing was never a professor, and his nickname 'Prof' was given by his codebreaking friends at Bletchley Park. Now Dermot Turing has taken a fresh look at the influences on his uncle's life and creativity, and the creation of a legend. For the first time it is possible to disclose the real character behind the cipher-text: how did Alan's childhood experiences influence the man? How did his creative ideas evolve? Was he really a solitary genius? What was his wartime work after 1942, and what of the Enigma story? What is the truth about the conviction for gross indecency, and did he commit suicide? In Dermot's own style, he takes a vibrant and entertaining approach to the life and work of a true genius.
