A story written by World War Two codebreaker Alan Turing suggests he was a man with playful humour embracing his homosexuality, according to new analysis. Dillon said the story offered fresh insights that challenge the view of Turing as an isolated, lonely genius. "We've distilled a version of Turing that is a two-dimensional stereotype," she added. Turing played a crucial role in the Allies' victory over Nazi Germany in World War Two by helping to crack codes and deciphering the infamous Enigma machine at Bletchley Park. After the war he produced a detailed design for a digital computer in the modern sense, storing programmes in its memory.
