This series primarily includes photographs of N-YHS's building on Central Park West (1909-present) and, to a lesser extent, its earlier home on 2nd Avenue (1857-1909). There are photographs of the Central Park West building from both before and after the major expansion and renovation of the building in 1937-1938. Both the early twentieth century and 1930s construction projects at Central Park West are documented. The series includes both interior and exterior views.
The series also includes a small number of images of N-YHS's various homes from 1804 to 1857. And the series includes images of Richard Morris Hunt's proposals of the 1860s for a building in Central Park for N-YHS and of the summer museum N-YHS maintained at the Thompson homestead on Long Island from 1942-1946.
