Founder of computer science, mathematician, philosopher, and
codebreaker extraordinaire, Turing was the first to have the idea of using machines to do computations. As a codebreaker, he played a key role in cracking the German Enigma code during WWII. He was at the forefront in the development of computer and software design, programming, neural nets, and artificial intelligence. The world as we know it now owes a lot to this man, an acknowledged genius, who was so heinously persecuted to his death for being a gay man in a hypocritical society.
