Alan Mathison Turing, OBE, FRS ( 23 June 1912 – 7 June 1954), was an English mathematician, logician, cryptanalyst, and computer scientist. He was highly influential in the development of computer science, providing a formalisation of the concepts of "algorithm" and "computation" with the Turing machine, which played a significant role in the creation of the modern computer. Turing is widely considered to be the father of computer science and artificial intelligence.

Alan Turing’s Reading List: What the Computing Pioneer Borrowed From His School…
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.
