Stuart Symington was born in Massachusetts in 1901 and raised in Baltimore. He enlisted as a private at 17 in World War I and became one of the Army’s youngest second lieutenants, though the war ended before he went overseas. After Yale and a string of manufacturing jobs he married Evelyn Wadsworth, and in 1938 he took over Emerson Electric in St. Louis, turning it into the world’s largest maker of airplane gun turrets and racially integrating its workforce. Harry Truman brought him into government, and in 1947 he became the first Secretary of the newly independent Air Force, backing the Air Force Academy and overseeing the Berlin Airlift.

He resigned in 1950 when the administration refused the defense increases he sought after the Soviet atomic test, then won Truman’s old Missouri Senate seat in 1952. He publicly defended accused clerk Annie Lee Moss against Joseph McCarthy and helped lead the censure effort. His 1960 presidential run, backed by Truman, failed as he skipped primaries and refused to address segregated audiences. He served on Kennedy’s ExComm, refused to sign the Southern Manifesto and backed the major civil rights laws. He resigned a week early in 1976 to give John Danforth a seniority edge, and died in 1988.
