In addition playing major league ball for the Cleveland Indians, the Washington Senators, and the Sox (both Red and White), Berg graduated from Columbia Law School, studied Latin, Greek, French, German, Italian, and Sanskrit, served as an OSS agent during WW2 where he had a major role in the U.S.'s decision to back Tito over other resistance leaders and the opportunity to terminate physicist Werner Heisenberg. "Terminate ... with extreme prejudice." All of Berg's adventures can be read about at J*Grit: The Internet Index of Tough Jews.
