The document provides biographical information about three US Presidents from the 1920s - Harding, Coolidge, and Hoover - and discusses Hoover's background and career prior to becoming President. It notes that Harding won the presidency with 60% of the vote but had a scandal-plagued administration. Coolidge became president after Harding's death and pursued an isolationist foreign policy with tax cuts and limited aid to farmers. The document focuses on Hoover's career as a mining engineer, his relief work during World War I and aftermath in Belgium, his role leading US agricultural production during the war, and his position as Secretary of Commerce under Harding and Coolidge.
