Alan Turing was a pioneering British mathematician, logician, computer scientist, and cryptanalyst who is considered the father of modern computing and artificial intelligence. In 1948, Turing developed the concept of the Turing machine, a theoretical model of computing, and is widely known for his role in breaking the German Enigma code in World War II.
