pe, returning in 1910 to Chicago and Wisconsin where he began construction on his second home, Taliesin in 1911. The year 1913 brought Frank a contract for Midway Gardens in downtown Chicago, an entertainment park on the south side of Chicago which exists today only in the original plans and drawings.The Imperial Hotel project provided Wright with an engineering problem as well as an architectural challenge. Finished in 1922, the Imperial hotel was criticized for its aesthetic design, but when it survived a 1923 earthquake, which left the majority of Tokyo in rubble, it found praise. Wright had managed to design a "floating foundation" for the building which combined oriental simplicity, in modern world comfort. This was one of the few periods in Wright's life were his financial situation was at a positive level. Returning to the United States in 1922, Wright pursued the use of a new material in residential homes, concrete. Most of these "textile block" houses were built in California with a Mayan and Japanese influence. Though some claimed that Wright had peaked in 1910, with the Prairie houses, others claimed that in 1924 Wright's development was only just beginning.A 1932 autobiography sparked new interest in the architect and pulled Wright out of a plateau in his work with two of his most famous buildings: Fallingwater, Edgar J. Kaufmann's home in Bear Run, Pennsylvania, and the Johnson Wax Company Administration Building in Racine,Wisconsin. Wright's last "style", Usonian, was caused by a shift in society in the 1930's. Adapting architecture to the simple and economically tight lives of families in the 1930's, Wright used down scaling to bring the house to a more appropriate human level and reflect the informal and comfortable lives of the average American family. The Wright Fellowship was opened in 1932, welcoming apprentices to live, learn, and work at Taliesin, an idea comparable to that of a medieval manorial estate, and reflec...
