Pedro E Guerrero began his career as an architectural photographer in 1939, working for Frank Lloyd Wright at Taliesin West in Arizona. He went on to photograph the work of many other architects and sculptors, and he continued working for Wright until the latter's death in 1959; but his first photographs of architecture remained, in his own view, among his best work.This catalog is the record of an exhibition of Guerrero's photographs of the original Taliesin West, outside Scottsdale, and the Pauson House, outside Phoenix. Because Taliesin West stands now in much altered form and the Pauson House is lost, these images have great historical importance. Beyond that, they are also superb examples of photographic art. Admirers of Wright's work will find that this collection of historical images, many never published before, provides invaluable information on two major works from one of Wright's most productive periods. Bernard Michael Boyle is Professor of Architecture and Humanities at Arizona State University, where he teaches classes in the history of architecture. He is the editor of three previous volumes in the series. No. 4 in the series School of Architecture Historical Publications.
