"Machines take me by surprise with great frequency.”
Alan Turing was born on 23 June, 1912, in London. His father was in the Indian Civil Service and Alan parents lived in India until his father's retirement in 1926. Alan and his brother stayed with friends and relatives in England. Alan studied mathematics at Cambridge University, and subsequently taught there, working in the burgeoning world of quantum mechanics. It was at Cambridge that he developed the proof which states that automatic computation cannot solve all mathematical problems. This concept, also known as the Turing machine, is considered the basis for the modern theory of computation.
