AlanTuring.net. Alan Turing. English mathematician and computer scientist Alan Mathison Turing OBE FRS (; 23 June 1912 – 7 June 1954) was an English[6] mathematician, computer scientist, logician, cryptanalyst, philosopher, and theoretical biologist.[7] Turing was highly influential in the development of theoretical computer science, providing a formalisation of the concepts of algorithm and computation with the Turing machine, which can be considered a model of a general-purpose computer.[8][9][10] Turing is widely considered to be the father of theoretical computer science and artificial intelligence.[11] Despite these accomplishments, he was never fully recognised in his home country during his lifetime due to his homosexuality and because much of his work was covered by the Official Secrets Act.
After the war Turing worked at the National Physical Laboratory, where he designed the Automatic Computing Engine. Alan turing.
