ISAAC TICHENOR was born in Newark, New Jersey. He graduated from Princeton in 1775 and studied law in upstate New York, after which he moved to Bennington, Vermont to practice his profession. In 1777 he was appointed Assistant Commissary and bought supplies for the Northern Department of the Continental Army. After being acquitted of the charge of misusing his purchasing powers, he went on to become a member of the State House of Representatives from 1781 to 1784, serving as speaker in 1783. In 1782 he presented Vermont’s claim to the U.S. Congress for admission to the Union. He also served on the Vermont-New York Joint Boundary Commission of 1789 and was a member of the State Council of Censors in 1792 and 1813. He went on to become a State Supreme Court Justice, serving as an associate justice from 1791 to 1794 and as Chief Justice in 1795 and 1796. In 1796 he was selected to fill an unexpired term in the U.S. Senate and was reelected the following year for a full six-year term but resigned after winning the governorship. In 1814 he was again elected to the U.S. Senate, where he served until 1821, when the Federalist Party of which he was a member became extinct.
