Watt-Pinkney Mansion, 1925.

Built in 1796 by John DeLancey, the dwelling later known as the Watt-Pinkney mansion originally stood on a low rise of what would become 139th and 140th Streets. Archibald D. Watt acquired the house and its 300-acre farm in 1826. Eleven years later, following the crash of 1837, he borrowed funds from his stepdaughter, Mary G. Pinkney (1810-1908). A mortgage on the Watt acreage secured the loan. In the 1860s, when Seventh Avenue was extended northward, the house was moved around the corner to 139th Street.

Mary G. Pinkney left a fortune in uptown real estate and a house worthy of becoming a museum. However, her home was not to enjoy the fate of the Morris-Jumel Mansion. Around 1915 the Libya nightclub opened in the mansion near the foot of Libya Hill. Harlem’s most influential politicians, professionals, and theater people patronized the club, where the Clef Club provided the musicians. A young Ethel Waters, famous later as a singer and then as an actress, performed at the Libya as part of a dance duo. The nightclub closed in 1921. For a time, the local community tried to interest the City of New York in acquiring the property for a playground, but the house was ultimately demolished in 1925.
