Wright strongly believed in working alone. He did not support the American Institute of Architects during his career, going so far as to call the organization "a harbor of refuge for the incompetent," and "a form of refined gangsterism." When an the Institute called him "an old amateur" Wright later responded, "I am the oldest." In 1940, Wright started the Frank Lloyd Wright Foundation. It was set up for educational purposes. It looks after two Wright buildings, Taliesin East in Wisconsin, and Taliesin West in Arizona. It has a library with more than 22,000 of Wright's drawings, and 300,000 documents. It is home to the Frank Lloyd Wright School of Architecture.
