Barry Bergdoll is the Meyer Schapiro Professor of Art History at Columbia University. Professor Bergdoll’s broad interests center on modern architectural history. Trained in art history rather than architecture, he has an approach most closely allied with cultural history and the history and sociology of professions. He has studied questions of the politics of cultural representation in architecture, the larger ideological content of nineteenth-century architectural theory, and the changing role of both architecture as a profession and architecture as a cultural product in nineteenth-century European society. In exhibitions at the Canadian Centre for Architecture and at the Museum of Modern Art, where he served as Philip Johnson Chief Curator from 2007 to 2013, Bergdoll has offered a series of exhibitions intended to offer more inclusive visions of subjects from Mies van der Rohe (and his relationship to garden reform and landscape), the Bauhaus, Henri Labrouste, Le Corbusier, Latin American post-war architecture, and most recently Frank Lloyd Wright. 

Emily A. Beeny is the Curator in Charge of European Paintings at Fine Arts Museums of San Francisco.

Paul Getty Museum in Los Angeles, California.
