On the occasion of Turing’s would-have-been-100th birthday, researchers don’t think that he committed suicide. Rather, they believe that his death occurred when an electroplating experiment went wrong or chemicals were accidentally transferred to his food.
Turing expert Prof Jack Copeland… believes the evidence would not today be accepted as sufficient to establish a suicide verdict. …a coroner these days would demand evidence of pre-meditation before announcing a verdict of suicide, yet nothing in the accounts of Turing’s last days suggest he was in anything but a cheerful mood.
Turing was a mathematical genius and codebreaker who contributed to Britain’s success in World War II.
