Alan Turing

Alan Mathison Turing OBE FRS was a pioneering English computer scientist, mathematician, logician, cryptanalyst and theoretical biologist. He 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. Turing is widely considered to be the father of theoretical computer science and artificial intelligence.

Turing was born in Maida Vale, London, while his father, Julius Mathison Turing , was on leave from his position with the Indian Civil Service at Chhatrapur, Bihar and Orissa Province, in British India. Turings father was the son of a clergyman, the Rev.160John Robert Turing, from a Scottish family of merchants that had been based in the Netherlands and included a baronet. Turings mother, Julius wife, was Ethel Sara , daughter of Edward Waller Stoney, chief engineer of the Madras Railways. The Stoneys were a Protestant AngloIrish gentry family from both County Tipperary and County Longford, while Ethel herself had spent much of her childhood in County Clare.
