This man, Alan Turing, helped win World War II by inventing a computer than could decrypt German messages encoded with the Enigma machine. In addition, he formally described the concepts of algorithms and computation. He proved that anything computable on one machine, is computable on another, given enough time. He is the father of computer science. After the war he was tried in court for being gay, found gulty, forced to take castration pills, and then driven to suicide. Britan has apologised.
