Peter Leffert, who built the house in 1783, served in the Revolutionary War as a lieutenant in the Continental Army. He later was part of the New York convention responsible for ratifying the Constitution in 1788. He passed the home onto his son when he died. The house remained in the family until 1918.
The City of New York accepted the house from the Leffert family in 1918, after years of urban encroachment threatened the home's future. The house was moved to Prospect Park that same year, and it was turned into a museum in 1920 by the Daughters of the American Revolution. Owned by the New York City Department of Parks & Recreation, the museum provides an example of what family life was like in the 1820s. It was designated a city landmark in 1966.
