Collection Overview
- Description
-
Primarily architectural subjects, including interiors and exteriors of
homes, stores, offices, factories, historic buildings, and other
structures. Subjects are concentrated chiefly in the northeastern United
States, especially the New York City area, and Florida. Included are the
homes of notable Americans, such as Raymond Loewy, and of several U.S.
presidents, as well as color images of the 1939-40 New York World's Fair.
Many of the photographs were commissioned by architects, designers,
owners and architectural publications, and document important
achievements in American 20th-century architecture and interior design.
