According to Wikipedia, Alexander Hamilton (January 11, 1755 – July 12, 1804) was the first United States Secretary of the Treasury, a Founding Father, economist, and political philosopher. Aide-de-camp to General George Washington during the American Revolutionary War, he was a leader of nationalist forces calling for a new Constitution; he was one of America's first Constitutional lawyers, and wrote most of the Federalist Papers, a primary source for Constitutional interpretation. Hamilton was the primary author of many of the policies supported by the Federalist Party.
