Moe Berg appears as a Great Spy in Civilization IV. He began his career as a catcher in major league baseball, where he was known as "the brainiest guy in baseball" (studied seven languages at Princeton University, many successful appearances on radio quiz shows). When America entered World War II, he served as a spy for the Office of Strategic Services. Among his accomplishments: gathering intelligence on resistance groups for America to support and discerning the status of the German nuclear programs, with orders to kill Werner Heisenberg if Germany was making any significant progress.
