Marks the centenary of the birth of the British Mathematician, Alan Turing.
He is considered to be the father of computer science and artificial intelligence.
Turing was educated at Cambridge and Princeton. In 1937 he described a theoretical computer (a Turing machine) in rigorous mathematical terms, formalising the previously vague concept of computability.
During the Second World War he worked as a code breaker at Bletchley Park, Britain's codebreaking centre. In 1939-40 Turing and Cambridge mathematician, Gordon Welchman, designed the British Bombe, which could break any Enigma-enciphered message.
In later years he worked on Artificial Intelligence, devising the Turing test to decide whether a computer can be thought of as truly 'intelligent'. Turing was prosecuted in 1952 for his homosexuality, which was a criminal offence at the time. He later committed suicide in 1954.
The last 2 years of his life were devoted to mathematical biology and natural pattern formations.
