857 Riverside Drive, November 16, 1937. This charming 19th century, wood-frame home with a widow's walk on the roof remains standing though with some serious alterations. The widow's walk and porch have been removed and the clapboard replaced with faux brick siding. The current cornice and chimney seem to match with the details of this 1937 photograph.

Willam A. Wheelock Mansion ca. 1937 This Second Empire-style mansion, located at 661 West 158th Street with grounds spreading from West 158th to 160th Streets, was built about 1860 for businessman William Almy Wheelock. The Wheelock House withstood the incursion of the 1904 Riverside Drive extension, which was curved inward toward the east to avoid the charming villas of Audubon Park. Laid out around an oval park with a white marble fountain group, the Drive tended to isolate the houses, which were gradually replaced by apartment houses. Almost the last of the old places to survive was 661 West 158th Street. It was finally demolished in 1938, just a year after photographer Berenice Abbott documented it, for Riverside Houses, a low-income housing project.

Riverside Drive West and the Hudson River, ca. 1941. The original route of Riverside Drive made a sharp turn to the right at 155th Street, bisecting Audubon Park, and isolating “Minnie's Land,” John James and Lucy Audobon’s former home, well below street level to the west of the new road. Upon the opening of the new curved roadway in 1911, motorists complained about the succession of sharp turns. As a solution, the city built a new viaduct between 155th and 161st Streets. Opened in 1928, the viaduct today carries Riverside Drive West.

The naturalist John James Audubon is best known for "The Birds of America," the comprehensive, hand-painted ornithological survey published between 1827-1839, but it was his 1841 purchase of a riverfront estate that came to influence the development of Washington Heights, Riverside Drive, and Upper Manhattan beyond the Commissioner’s Plan grid.

William A. Wheelock Mansion, photographed by Berenice Abbott in November 1937. In 1862, Wheelock, a dry goods wholesaler, purchased a riverside parcel of the Audubon estate that stretched from 157th to 159th Street. There, he build a Victorian mansion, complete with a bell-shaped mansard roof, Gothic details, and extensive gardens. The city purchased the by-then overgrown Wheelock property in 1941, tearing the buildings down to make room for a housing development.

This endangered two-story wood-frame house at Riverside and West 159th Street, is believed to have a connection to the Underground Railroad and upper Manhattan’s little-known Abolitionist history.
