The Automatic Computing Engine, the first step for intelligent computers

Alan Mathison Turing, (23 June 1912 – 7 June 1954) was an English mathematician, logician and cryptographer. Turing is often considered to be the father of modern computer science.

From 1945 to 1947 Alan Mathison Turing was at the National Physical Laboratory, where he worked on the design of the ACE (Automatic Computing Engine). He presented a paper on 19 February 1946, which was the first detailed design of a stored-program computer. While he was at Cambridge, the Pilot ACE was built in his absence. It executed its first program on 10 May 1950. Turing addressed the problem of artificial intelligence, and proposed an experiment now known as the Turing test, an attempt to define a standard for a machine to be called "intelligent". The idea was that a computer could be said to "think" if it could fool an interrogator into thinking that the conversation was with a human.
