Professor Jack Copeland, an expert on the life of Alan Turing, believes there’s no evidence that Turing committed suicide.
Turing was found dead in his bed from cyanide poisoning on June 7th, 1954. He was 41 years old. Two years earlier he had been prosecuted for gross indecency after his homosexuality came to light during a police investigation into a burglary. Turing had agreed to be treated with female hormone in lieu of prison, and this “chemical castration” was widely believed to have sent him into a spiral of depression that culminated in his death. Because of his alleged obsession with Disney’s Snow White, he chose to die by reenacting the “poison apple” scene from the film. (It was assumed that the partially eaten apple by his bedside was laced with cyanide, but the apple was never even tested.)
