Gouverneur Morris I (January 31, 1752 – November 6, 1816) was an American statesman, a Founding Father of the United States, and a native of New York City who represented Pennsylvania in the Constitutional Convention of 1787. He was a signatory to the Articles of Confederation. Morris was also an author of large sections of the Constitution of the United States and one of its signers. He is widely credited as the author of the document's preamble, and has been called the "Penman of the Constitution." In an era when most Americans thought of themselves as citizens of their respective states, Morris advanced the idea of being a citizen of a single union of states.
