Andrew Mellon, a titan of industry in the 19th and 20th centuries, has been lambasted as a “robber baron” who manipulated government and exploited the common man for personal interests. However, Mellon was an influential figure who used sound economic judgement to further the growth of the American economy in the 1920s. The project will investigate the economic policies Andrew Mellon implemented or influenced as Secretary of Treasury. I will primarily use historical research methods at the Arizona State University’s library to complete a final paper. The Coolidge Foundation and Ms. Amity Shlaes, a trustee of the foundation and author of the biography Coolidge, will contribute perspectives of Mellon during his tenure as Secretary of the Treasury. I will contact economics, political science and history professors in local state universities to advise me on my research. The Andrew W. Mellon Foundation and authors who have conducted in-depth research into Mellon’s life will also add to my research on Mellon’s role as a policymaker and everyday citizen. Blogging on the foundation’s website will expand the scope of my research and reveal lessons from various aspects of Mellon’s life. By consolidating these historical perspectives and analyzing them in contrast with the relevant economic and historical data, I hope to make conclusions about policy that can be utilized to strengthen America’s modern economy.
