The first in-depth study of one of the seminal works of America's most renowned twentieth-century architect, first published in 1996, is now available in paperback. In this study, Joseph Siry examines the building in the light of Wright's earlier religious architecture, his methods of design, and his innovative construction techniques, particularly the use of reinforced concrete which was here exploited and expressively deployed for the first time. He also sets Unity Temple against the tradition of the liberal Unitarian and Universalist religious culture, the institutional history of the affluent Oak Park congregation that commissioned the building, as well as the social context in which structure was conceived and built. Throughout, Unity Temple is treated as a work of art that embodies both Wright's theory of architecture and his liberal religious ideals.
