The Office of Strategic Services (OSS) left a legacy of daring and innovation that has influenced American military and intelligence thinking since World War II. OSS owed its successes to many factors, but most of all to the foresight and drive of William J. Donovan, who built and held together the office's divergent missions and personalities.
Alan Turing—an English mathematician, logician, and cryptanalyst—was a computer pioneer. Often remembered for his contributions to the fields of artificial intelligence and modern computer science (before either even existed), Turing is probably best known for what is now dubbed the "Turing Test." It is a process of testing a machine's ability to "think."
By the fall of 1944, it was obvious that the war in Europe was in its final year. In France, British and American forces had broken out of Normandy and were driving toward Paris and the Rhein.

All over the Continent, Allied domination of the air was complete, and in the North Atlantic the back of the German U-Bootwaffe was finally broken.
