Frank Lloyd Wright established the Taliesin Fellowship in 1932.1

This program served as a training initiative for architects and artists who lived and worked at Taliesin, participating in the maintenance and development of the estate's buildings. Each year, between 20 and 60 apprentices worked alongside Wright, with the group eventually traveling to Arizona during the winter months, where they would later construct Taliesin West.1
