Which delegate signed the Constitution as president of the Constitutional Convention?

George Washington signed the Constitution as president of the Constitutional Convention.

Washington presided over the Philadelphia convention, which met from May to September 1787 to replace the weak Articles of Confederation. Although he participated in the discussions, his most visible role was chairing the proceedings and maintaining order among delegates representing the states.

The Constitution was signed at the Pennsylvania State House, now Independence Hall, on September 17, 1787. Thirty-nine delegates signed the document, and Washington’s signature appears first. Three delegates who were still present declined to sign: George Mason, Edmund Randolph, and Elbridge Gerry.

Washington’s convention role helped establish his reputation as a unifying national figure. Two years later, he became the first president of the United States. His later presidency also influenced the emerging tradition that presidents should serve as national, rather than narrowly regional, leaders.
