The Mind Creative Later, Turing held high-ranking positions in the mathematics department and the computing laboratory at the University of Manchester in the late 1940s. Here, he first addressed the issue of artificial intelligence in his 1950 paper, "Computing machinery and intelligence," and proposed an experiment known as the “Turing Test” - an effort to create an intelligence design standard for the technology industry. Interestingly, this particular test continues to influence discussions and debates on artificial intelligence. Homosexuality, Conviction and Death In the 1950s, homosexuality was illegal in the United Kingdom. In January 1952, after a break-in at his house, Turing admitted to the police that he had had a sexual relationship with the perpetrator; a 19-year-old Arnold Murray. Turing was charged consequently with gross indecency. Following his arrest, Turing was forced to choose between temporary probation on the condition that he receives hormonal treatment for libido reduction, or imprisonment. He chose the former, and soon underwent chemical castration through injections of a synthetic oestrogen hormone for a year, which ultimately rendered him impotent. As a result of his conviction, Turing's security clearance was removed and he was barred from continuing his work with cryptography at the GCHQ. Turing died on June 7, 1954 – 16 days before his 42nd birthday. A post-mortem exam revealed that the cause of death was cyanide poisoning. 11
