George Shaw Wheeler (May 22, 1908 – October 18, 1998) (known also as George S. Wheeler) was an American economist and advisor to President Franklin Delano Roosevelt, best known for being the first American to defect over the Iron Curtain to Czechoslovakia in November 1947. Wheeler's defection inspired his friend Noel Field to do likewise the following year in 1949 and also US Senator Joseph McCarthy cited Wheeler's name when accusing US President Harry S. Truman of "Trumanism", i.e., "the placing of your political party above the interest of the country", specifically when it came to promoting alleged Communist spy Harry Dexter White and others (including Wheeler).
