Hammond was a
New York City merchant and a director of both the
Bank of New York (later becoming BNY Melon) and the
Society for Establishing Useful Manufactures. Long Island, and upstate New York. The town of
Hammond, New York is named after him. Over his lifetime starting in 1793, eight hundred transactions were recorded, mostly in New York City and New York County locations. Typically, he bought and subdivided the land, selling parcels to individuals of all walks of life. In 1792, Hammond donated a device for drilling for water to the New York City government, which ordered experiments to begin on a vacant lot adjoining city hall. On November 7, 1796, the
20th New York State Legislature elected 12 presidential electors, all Federalists. One of the 12 was Abijah Hammond. Hammond and the others all cast their votes for
John Adams and
Thomas Pinckney. He was also an avid reader, especially of books relating to the ancient societies in and around the Mediterranean. Hammond was a commissioner at the first meeting of the
New England Society of New York in 1805. In 1799, Hammond was the "second" for
John Barker Church in the duel between Church and
Aaron Burr. Church was the brother in law of
Alexander Hamilton. Hamilton subsequently died in his duel with Burr in 1804. In the New York City "pig wars" of the 1810s, Hammond mobilized two hundred fellow merchants and property owners to sign a petition demanding the removal of all free-running pigs. Although this effort did not immediately sway the city council, the pigs and their owners were eventually driven out to New Jersey ==New York Manumission Society==
