Herbert Hoover
Herbert Clark Hoover was the 31st president of the United States, serving from 1929 to 1933. A wealthy mining engineer before his presidency, Hoover led the wartime Commission for Relief in Belgium and was the director of the U.S. Food Administration, followed by post-war relief of Europe. A member of the Republican Party, he served as the U.S. Secretary of Commerce from 1921 to 1928 before being elected president in 1928. His presidency was dominated by the Great Depression, and his policies and methods to combat it were seen as lackluster. Amid his unpopularity, he decisively lost reelection to Franklin D. Roosevelt in 1932.
