Wright and Olgivanna began the Taliesin Fellowship, taking on apprentices. Fallingwater brought him new acclaim for its modern principles and materials integrated with the landscape. Usonian houses were high-quality, affordable housing for mass production. In 1937, the Fellowship began annual pilgrimage to Arizona's Taliesin West. His provocative postwar gas stations, synagogues, and a spiral-ramped Guggenheim Museum, closed out his career. Directed by Ken Burns and Lynn Novik.
