As World War II continued to rage in December 1944, German physicist Werner Heisenberg conducted a lecture at a college in Zurich. Heisenberg was thought to be the brains behind Nazi efforts to build an atomic bomb.
In the crowd sat a former Major League Baseball catcher who hit .243 during 15 seasons with just six home runs in 1,813 at-bats.
That day, Moe Berg carried a pistol and cyanide pill as an undercover member of the Office of Strategic Services — the spy-craft predecessor of the CIA. His dangerous and daring assignment: Assess whether Heisenberg and the Germans were close to solving the atomic riddle and, if so, assassinate him on the spot.
