Dearborn-Massar was a mid-20th-century American firm specializing in architectural photography founded by Phyllis Dearborn (1916–2011) and Robert J. Massar (1915–2002).
[2][3] Her style was influenced by the F/64 group of photographers that coalesced around Ansel Adams, with whom she took courses at the Museum of Modern Art in New York.
They shot negatives and transparencies of the interiors and exteriors of both homes and businesses, and their oeuvre profusely documents the regional version of modernist architecture that is sometimes called the Northwest Contemporary style.
[3] Architects whose work they photographed include Ralph Anderson, Pietro Belluschi, Mary Lund Davis, J. Lister Holmes, Paul Hayden Kirk, Wendell Lovett, Ellsworth P. Storey, Victor Steinbrueck, Roland Terry, and Paul Thiry.
[2] An archive of their firm's work during the period 1943–1963, the Phyllis and Robert Massar Photograph Collection of Pacific Northwest Architecture, is held at the University of Washington.
