Alan Turing was a brilliant mathematician, logician and cryptographer. A Cambridge graduate who was fundamental to cracking the Nazi's Enigma Code during WWII, Turing created what is hailed by some as the first modern computer and was a legendary innovator in his field. He was also gay, and fell victim to the intolerance and legal prosecution of his time, as homosexuality was considered an extreme mental illness and subject to criminal sanctions in the UK.
Turing was pursued legally based on his sexual orientation, and eventually ruined professionally, exiled from his colleagues, and forced to undergo chemical castration in an attempt to "cure" him. Posthumously, Turing is lauded; universities around the world have programs and buildings in his name, and, since 1966, the Turing Award has been given each year by the Association for Computing Machinery, widely considered to be the computing world's equivalent to the Nobel Prize.
