Book excerpt: Beginning with Paul Strand’s landmark From the Viaduct in 1916 and continuing through the present day, Photography’s Last Century examines defining moments in the history of the medium. Featuring nearly 100 masterworks from one of the most important private holdings of photography, the book includes works by Diane Arbus, Richard Avedon, Walker Evans, László Moholy-Nagy, Man Ray, and Cindy Sherman, as well as a diverse group of important lesser-known practitioners. A fascinating interview with Ann Tenenbaum provides a personal account of the works, while the main text offers an essential history of photography that addresses the implications of calling this period the medium’s “last” century.
