Alan Turing slate statue at Bletchley Park museum

June 23 marks the 100th birthday of Alan Turing. If I had to name five people whose personal efforts led to the defeat of Nazi Germany, the English mathematician would surely be on my list. Turing's genius played a key role in helping the Allies win the Battle of the Atlantic—a naval blockade against the Third Reich that depended for success on the cracking and re-cracking of Germany's Enigma cipher. That single espionage victory gave the United States control of the Atlantic shipping lanes, eventually setting the stage for the 1944 invasion of Normandy.

## Alan Turing's Year

2012 is billed as the "Alan Turing Year," and a lengthy compendium of past and future Alan Turing events can be found at the Centenary site hosted by the United Kingdom's Mathematics Trust. The big gathering taking place right now is the Alan Turing Centenary Conference in Manchester.
