On this date in 1911, Henry L. Stimson took up his post as the 45th Secretary of War, appointed by Republican William Howard Taft. He served until the end of Taft's term, in 1913. Sixteen years later, in March 1929, Republican Herbert Hoover appointed Stimson the 46th Secretary of State, and he served the full four years of Hoover's term. In July 1940, Democrat Franklin Delano Roosevelt recalled Stimson to head the War Department, making him the 54th Secretary. Stimson resigned in September 1945, five months after Roosevelt's death, during Democrat Harry Truman's term. Stimson is the only person to serve in the Cabinet under four Presidents.
