In 1939, in the dry, desert foothills of the McDowell Mountain Range of Scottsdale, Ariz., a young man asked an older man for a job. The young man, a 22-year-old named Pedro E. Guerrero, was trying to start a career as a photographer. The older man, at 72, was Frank Lloyd Wright. At the time, Guerrero lacked a degree in photography and was unaware of Wright’s celebrity-architect status—he only knew that Wright was a man building a house in the desert (the house, of course, was Taliesin West). “I had no idea who this man was,” he says. “If I had known, I probably wouldn’t have gone.” It was perhaps this innocence that appealed to Wright and led to Guerrero’s career as the architect’s preferred photographer.
