Turing often seems to get most of the credit for ending the war early (probably due to the injustice he suffered), but we shouldn't forget others suffered in different ways.
Tommy Flowers (http://en.wikipedia.org/wiki/Tommy_Flowers), who arguably created the first electronic computer to decrypt the Lorenz cypher was just as important and his work was not acknowledged until the 1970s.
Flowers wanted to create a computer after the war but the Bank of England wouldn't lend him the money because they didn't believe it was possible and he couldn't disclose he'd already done it due to official secrets act.
Let's not forget the millions of Russians who died on the eastern front. Without them, nothing at Bletchley Park wouldn't have mattered much for ending the war.
