Author and preeminent Wright expert Bruce Brooks Pfeiffer highlights the latest research and gives fresh insight into the work. Volume 3 starts after World War II, when Wrights organic living architecture introduced ideas for the use of solar energy and curved open spaces. In addition to the Guggenheim museum, the postwar era also saw extraordinary projects such as Wrights plans for a new Baghdad, his only realized high-rise tower in Bartlesville, Oklahoma, the crystal figure of the Beth Sholom Synagogue in Elkins Park, Pennsylvania, and an endless row of houses that reached new complexity by floor plans based on hexagons.
