Alan Mathison Turing was born on June 23, 1912, in Maida Vale, London, to Julius Mathison Turing, a civil servant in the Indian Civil Service, and Ethel Sara Stoney. He studied mathematics at King's College, Cambridge, graduating in 1934, then earned his doctorate at Princeton University in 1938. His 1936 paper "On Computable Numbers" introduced the theoretical Turing machine, establishing foundational concepts for digital computation. Turing's subsequent work spanned cryptanalysis, mathematical biology, and early artificial intelligence research.
