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