American photographer Pedro E. Guerrero devoted half a century to documenting the work of architect Frank Lloyd Wright. Working first as Wright’s exclusive photographer, then returning frequently to photograph his buildings after the architect’s death, he became the primary visual interpreter of Wright’s work. Shooting exclusively in black and white, he focused on the relationship between modernist structure and the surrounding environment, paying particular attention to the play of light and shadow on both the surface and interior. Guerrero also collaborated with the sculptors Alexander Calder and Louise Nevelson, and architects such as Philip Johnson and Marcel Breuer.
