Melancton Smith (May 7, 1744 – July 29, 1798) was a merchant, lawyer and a New York delegate to the Continental Congress. Praised for his intelligence, liberality, and reasonableness, Smith had attained considerable respect in the State of New York by 1787 and he has been described by modern scholars as the most important Anti-Federalist theorist and spokesman. Additionally, Smith played an active and central role in the ratification of the U.S. constitution.
