Pedro E. Guerrero (1917–2012) spent his career of more than 60 years photographing the most illustrious American architects and artists of the 20th century, the most famous of whom was Frank Lloyd Wright. Following Wright’s death, Guerrero went on to document the groundbreaking modernist works of Marcel Breuer, Philip Johnson and Edward Durell Stone, as well as such legendary figures as Alexander Calder, Louise Nevelson, John Huston, Julia Child and Alexey Brodovich.
