Alan Turing

Definition

Alan Turing was a pioneering British mathematician and computer scientist who is widely considered the father of theoretical computer science and artificial intelligence. His groundbreaking work on the concept of algorithms and computation laid the foundation for modern computing, and he played a vital role in developing early computers, notably during World War II when he worked on breaking the German Enigma code. Turing's ideas have had a profound influence on the architecture of computers, particularly in the context of how they process information.
