Stuart Symington

Born in Amherst, Massachusetts, Symington worked as an executive in his uncle's iron products company and for other companies before becoming president of Emerson Electric. He resigned from Emerson in 1945 to take various positions in the administration of President Harry S. Truman, becoming the first Secretary of the Air Force in 1947. He was elected to the Senate in 1952, defeating incumbent Republican Senator James P. Kem. He joined the United States Senate Armed Services Committee and the United States Senate Committee on Foreign Relations, and emerged as a prominent critic of McCarthyism.

Symington sought the Democratic nomination in the 1960 presidential election with the backing of former President Truman, but the nomination went to John F. Kennedy. After the Kansas City Athletics moved to Oakland, Symington threatened to revoke Major League Baseball's antitrust exemption, which in turn encouraged the formation of the Kansas City Royals. Symington declined to seek re-election in 1976 and was succeeded by John Danforth.
