Alan Mathison Turing was born in London, England -
At 22, he is elected as a fellow at King's College in Cambridge. -
He publishes "On Computable Numbers, with an Application to the Entscheidungsproblem" which will be foundational in computer science -
He publishes "Computability and λ-Definability" which connects Turing machines with Alonzo Churches λ-Calculus. -
He finishes his Ph.D in computability, cryptology, and logic under Alonzo Church at Princeton University. -
At the beginning of World War II, He starts working at Bletchley Park, which is the UK's code breaking center -
He publishes "Systems of Logic Based on Ordinals" which expands his work to include ordinal logic and explores how his framework could be extended to transfinite sequences. -
He develops the electromechanical device known as the Bombe which significantly accelerates the decryption of the German Enigma machine. -
He and his team at Bletchley Park decrypt German Naval Enigma messages, which is critical for the Allied war effort. -
He contributes to deciphering the Lorenz cipher used by the German high command -
He is awarded the Order of the British Empire for his work during the war. -
He designs the Automatic Computing Engine, which is a stored-program computer, at the National Physical Library. -
He publishes "Computing Machinery and Intelligence" which introduces the Turing test, a crucial tool used in computer science today. -
He is prosecuted for homosexuality, which was illegal at the time in the UK, and chose chemical castration instead of imprisonment. -
He dies of cyanide poisoning, likely thought to be suicide.
