1. introduction History of a remarkable Man Call “Alan Turing”. Study Life. Work life during the world war 2 period. His achievement after the world war. His jail life leading to his dead. A Story video of Alan Turing

2. Study Life Alan Turing was born on 23 June, 1912, in London. Turing studied mathematics at Cambridge University. and subsequently taught there, working in the quantum mechanics. In 1936, Turing went to Princeton University in America, returning to England in 1938

3. Work life during the world war 2 period Enigma He began to work secretly part-time for the British cryptanalytic department. Government Code and Cypher School during world war II he took full-time work at its headquarters, Bletchley Park. he played a vital role in deciphering the messages encrypted by the German Enigma machine. German computer Enigma generated a constantly changing code which was impossible for people to decipher. Turing's one of the first steps toward a digital computer lead in a team that designed a machine known as a bombe - managed to crack Enigma's codes, giving the Allies the break they desperately needed in fighting Germany. He became a well-known and rather eccentric figure at Bletchley Bombe

4. His achievement after the world war After the war, He turned his thoughts to the development of a machine that would logically process information. He worked first for the National Physical Laboratory (1945-1948). In 1949 at Manchester University where he directed the computing laboratory and developed a body of work that helped to form basis field of artificial intelligence. which was later published in 1969. This was one of the first times the concept of artificial intelligence was raised

5. His jail life leading to his dead Turing was accustomed to being a non-conformist and felt marginalized because of his homosexuality. To avoid prison, he accepted injections of oestrogen for a year. In that era, homosexuals were considered a security risk as they were open to blackmail. He no longer work for GCHQ. He committed suicide by taking potassium cyanide on 7 June, 1954. official explanation was "moment of mental imbalance". His mother claimed he was embarrassed about his sexuality. When he died, He left the world a permanent legacy. Computers have revolutionized so many aspects of our world that today it is hard to imagine life without them.
