Alan Turing was the oddball genius who single-handledly broke the Enigma code, ended World War II, and was hounded to death by the ungrateful authorities over his homosexuality… right? Wrong, says his nephew Dermot Turing, who tells author and historian Guy Walters that his uncle’s story has been seriously distorted to fit in with modern-day obsessions - and that the story told in films such as The Imitation Game risks masking many of Alan Turing’s real achievements in the field of computer science.
