Roger Sherman (April 19, 1721 – July 23, 1793) was an early American politician, lawyer, and a Founding Father of the United States. Representing Connecticut, he is the only person to sign all four great state papers of the United States: the Continental Association, the Declaration of Independence, the Articles of Confederation, and the Constitution. He also signed the 1774 Petition to the King.
Born in Newton, Massachusetts, Sherman established a legal career in Litchfield County, Connecticut, despite a lack of formal education. After a period in the Connecticut House of Representatives, he served as a justice of the Superior Court of Connecticut from 1766 to 1789. Connecticut sent him to the Continental Congress, and he was a member of the Committee of Five that drafted the Declaration of Independence.
Sherman served as a delegate to the 1787 Philadelphia Convention, which produced the United States Constitution. After Benjamin Franklin, he was the second oldest delegate present at the convention.
