| Born in [[Maida Vale]], London, Turing was raised in [[southern England]]. He graduated at [[King's College, Cambridge]], with a degree in mathematics. Whilst he was a [[fellow]] at Cambridge, he published a proof demonstrating that some purely mathematical yes–no questions can never be answered by computation and defined a [[Turing machine]], and went on to prove the [[halting problem]] for Turing machines is [[Decision problem|undecidable]]. In 1938, he obtained his [[Doctor of Philosophy|PhD]] from the [[Princeton University Department of Mathematics|Department of Mathematics]] at [[Princeton University]]. During the [[Second World War]], Turing worked for the [[Government Communications Headquarters#Government Code and Cypher School (GC&CS)|Government Code and Cypher School]] (GC&CS) at [[Bletchley Park]], Britain's [[cryptanalysis|codebreaking]] centre that produced [[Ultra]] intelligence. For a time he led [[Hut 8]], the section that was responsible for German naval cryptanalysis. Here, he devised a number of techniques for speeding the breaking of German [[cipher]]s, including improvements to the pre-war Polish [[Bomba (cryptography)|bombe]] method, an [[electromechanics|electromechanical]] machine that could find settings for the [[Enigma machine]]. Turing played a crucial role in cracking intercepted coded messages that enabled the Allies to defeat the [[Axis powers]] in many crucial engagements, including the [[Battle of the Atlantic]].<ref name="bbc-copeland">{{cite news|last=Copeland|first=Jack|author-link=Jack Copeland|date=18 June 2012|title=Alan Turing: The codebreaker who saved 'millions of lives'|publisher=BBC News Technology|url=https://www.bbc.com/news/technology-18419691|url-status=live|access-date=26 October 2014|archive-url=https://web.archive.org/web/20141011045451/http://www.bbc.com/news/technology-18419691|archive-date=11 October 2014}}</ref><ref>A number of sources state that Winston Churchill said that Turing made the single biggest contribution to Allied victory in the war against Nazi Germany.
