Elbridge Gerry was a wealthy Massachusetts merchant who was active in opposing British rule in the years leading up to the Revolutionary War. He was elected to the Second Continental Congress, and signed both the Declaration of Independence and the Articles of Confederation. Gerry was an active participant in the Constitutional Convention in the summer of 1787, helping shape key aspects of the Constitution, including equal representation for states of all sizes in the United States Senate. He opposed the Three-Fifths Compromise. At the end of the Convention, however, he was one of three delegates who refused to sign the Constitution. His refusal was due to the lack of a Bill of Rights in the draft that the delegates were asked to sign. Later in his life, he became Governor of Massachusetts in 1810 and Vice President in 1813.
