Frank Lloyd Wright (1867–1959) was one of the fathers of modern architecture; his work helped define the modern era, had a widespread cultural influence, and remains highly influential today, half a century after his demise. The mature work of his final years is the subject of this monograph, including all his designs from that period, even those never built. Based on unlimited access to the Frank Lloyd Wright Archives in Taliesin, Arizona, this penetrating study gives an unrivalled overview of Wright\'s groundbreaking work and eventual \'starchitect\' status — included are drawings he made for an unrealized house intended for Marilyn Monroe and Arthur Miller.
