Moe Berg was known as "the smartest man in baseball" and the 15-season Major League player was also a spy, working during World War II for the United States Office of Strategic Services, the forerunner of the current CIA. Offered is a 1956 Moe Berg signed check. Berg was born in New York City, and he lived for much of his life in Newark, New Jersey. He graduated from Princeton University, a foreign language student and magna cum laude graduate. He also graduated from the Columbia University School of Law. Berg started his Major League career with limited playing time in 1923 with the Brooklyn Robins (Dodgers). He then played in the Major Leagues from 1926-39, mainly for the Boston Red Sox, the Chicago White Sox, and the Washington Senators. He was excellent defensively and an astute handler of pitchers, but he only batted a career .243, with only six home runs, and he was usually a team's second or third-string catcher, but a valuable man for his baseball knowledge and his work with pitchers. He also became an esteemed coach. It is believed by some that Berg also acted as a spy before World War II, particularly when he was part of a tour of Japan by United States Baseball All-Stars. It is thought that after World War II that he occasionally worked for the successors of the Office of Strategic Services, the U.S. Central Intelligence Agency. Berg was usually cordial and friendly with others, but very secretive. Casey Stengel called him "the strangest man in baseball." The offered check is drawn on the National Newark & Essex Banking Co., in the amount of one hundred dollars. The check was written to cash and dated 27 September 1956. Berg signed the check, in neatly written, blue fountain ink, as Morris Berg, his legal name. The check has been canceled. The check is in excellent condition. It has been encapsulated and PSA Certified as AUTHENTIC AUTO. The check is a fine remembrance for one of baseball's most unusual personages.
