Alan Turing (1912-1954)
Alan Turing was credited as a pioneer of computer science and developed the first computer, known as the Turing machine. He was a mathematician and was part of a team that cracked the enigma code during world war 2. He deciphered the messages using a machine called ‘the bombe.’ After the war he went to work for the National Physical Laboratory. His ideas of a computer that would be able to process information at high speeds were rejected by his colleagues. He went on to work at Manchester University where he came up with the concept of artificial intelligence.
He wrote the Turin test which would decide if something had artificial intelligence or not. . It was to determine whether or not a computer could think like a human brain. The Turing Test is successfully passed if a computer is mistaken for a human more than 30% of the time during a series of five-minute keyboard conversations.He laid the foundations for modern computers and the information technology revolution.
He was arrested and tried for homosexuality, which was a crime in his era. He died after eating an apple injected with cyanide. It was claimed that he had committed suicide.
