Riverside Drive, north from 165th Street, ca. 1915.

Washington Heights’ wooded, bucolic character would soon be disrupted by development. In 1921, the Harkness family donated a 22-acre plot between 165th and 168th Streets for what would become the campus of the Columbia-Presbyterian Medical Center. Today, the Milstein Hospital Building, built in 1988, occupies 165th Street between Riverside Drive and Fort Washington Avenue.
