The ca, 1783 Lefferts Historic House is located in the southeastern corner of Prospect Park. It was moved to this site in 1918 from its original location on Flatbush Avenue between Maple and Midwood Streets after being given to the city by the Lefferts family. Peter Lefferts (1753-1791), builder of the house, was an officer in the Continental Army during the American Revolution and later a delegate to the Constitutional Convention and one of the wealthiest men in Kings County. Peter's descendant, John Jeffers (1827-1893) was no only a principal of the Flatbush Water Works and the Flatbush gas Company, but was also a director of three of the county's banks. The Lefferts House has been operated as a museum since 1920 and represents the large, finely appointed Dutch-American farmhouses that evolved in the later 18th century as Dutch families adapted elements of English Georgian architecture and decoration, such as the two-tiered gambrel roof and the central hall.
