Some historians estimate that the work done at Bletchley Park shortened the war by as much as four years. (PROSE: A History of Humankind)

Alan Turing was chief cryptologist at Bletchley Park until he left to work at Hanslope Park. Hugh Alexander replaced him, but called Turing back in December 1944 after discovering a new code being transmitted from Dresden. With the help of the Eighth Doctor, they discovered that the code was alien in origin. (PROSE: The Turing Test) Turing's team was known as the Cambridge Group; its most notable member was Rachel Jensen.
