Andrew Mellon

Andrew William Mellon (1855 to 1937) was an American banker, industrialist and philanthropist who helped build several major American industrial enterprises before turning to public life. He helped establish and finance the Guffey Company, which was reorganized in 1907 into Gulf Oil, one of the major oil companies of the twentieth century, and he was also instrumental in developing aluminum production through his investment in the Pittsburgh Reduction Company, later renamed Alcoa. Mellon went on to serve as United States Secretary of the Treasury from 1921 to 1932 under three consecutive Republican presidents, overseeing economic policy through the prosperity of the 1920s and into the onset of the Great Depression.
