King Manor

Rufus King was a delegate from Massachusetts to the Continental Congress and the Philadelphia Convention and one of the signers of the United States Constitution in 1787. He successfully added provisions to the 1787 Northwest Ordinance that barred the extension of slavery into the Northwest Territory, and he was an abolitionist and paid his workers. As the de facto Federalist nominee for president in 1816, he lost in a landslide to James Monroe. Wikipedia says the manor "is owned and maintained by the New York City Department of Parks and Recreation, and its interior furnishings are supervised by the King Manor Association"; the museum's own site says it is "owned by the City of New York, operated by the King Manor Association of Long Island, Inc."
