John Hanson, 1715–83, first
"President of the United States in Congress Assembled,"
b. Charles co., Maryland. He served in the Maryland provincial legislature, was active in the patriot cause in the Revolution, and was (1780–82) a member of the Continental Congress. Since he was the first President to serve the one-year term (1781–82), under the Articles of Confederation, Hanson is sometimes referred to as the first President of the United States. His duties were, however, merely those of a presiding officer and bore no relation to the duties of the President under the Constitution.
