Alan Turing

Alan Turing was born in London on 6/23/1912. He formalized the concepts of an algorithm and computation with the Turing Machine. This Turing Machine was a mathematical model of coputation and defined an abstract machine. It gave a foundation of research in the Artifical Intelligence (AI) field and contained the fundamental principles of our modern-day computers. He is widely regarded as the "Father of Theoretical Computer Science and AI". He was gay, so much of his work, including his as a code-breaker work in WW2, was kept secret.
