I had no idea that the assassination of Werner Heisenberg nearly came to pass.

'In November 1944, the OSS learned that Heisenberg planned to visit Switzerland the next month. Former major league baseball catcher and then OSS officer Moe Berg was dispatched to Zurich with orders that “Heisenberg must be rendered hors de combat” (out of action) if Heisenberg gave evidence that the German bomb effort was close to completion. Apparently Berg alone was to decide whether or not to kill Heisenberg.'
