Following his graduation in 1794, Jay acted as private secretary to his father in London for the
Jay Treaty. The young Jay studied law and established a practice in New York City with his cousin
Peter Jay Munro, carrying on a family tradition of public service. As a
Federalist, he was a member from New York City of the
New York State Assembly in the
39th New York State Legislature, during which time he was active in arranging the financing for the construction of the
Erie Canal. He ran many times for Congress, but was always defeated by the
Democratic-Republican candidates. From 1819 to 1821, he was
Recorder of New York City. He was a delegate from Westchester Co. to the
New York State Constitutional Convention of 1821. For a time he was also a Westchester County Judge.
Philanthropy and Affiliations In 1814, Jay and his father were both elected members of the
American Antiquarian Society. Together with financier
Thomas Eddy, Peter Augustus Jay also helped organize and found New York's earliest savings bank, the now defunct
New York Bank for Savings in 1816 (thereby contributing to the establishment of the New York State savings bank system). In 1828, he helped found the
New York Law Institute, which today is the oldest law library in New York City. Jay was President of New York Hospital (1827–1833), Chairman of the Board of Trustees, King's College and President of the
New-York Historical Society (1840–1842). In 1832, he was honored with a Doctor of Laws from
Harvard University for his "talents and virtues", and from Columbia, in 1835. Jay is best known for giving a speech in 1821 at the
New York State Constitutional Convention as a delegate arguing that the right to vote should be extended to free African Americans. "Peter Augustus Jay, one of a minority of advocates of universal manhood suffrage, insisted that the idea that black people were naturally inferior had long been 'completely refuted and universally exploded.'" Despite his impassioned argument, Jay's motion for extending suffrage was overruled. == Personal life ==
