This monograph explores the underlying themes and principles of Frank Lloyd Wright's architecture. It examines the consistent and systematic qualities underlying all of Wright's designs. The text's chronological presentation, which emphasizes key designs and those related to them thematically, is paralleled by an examination of the development of three primary principles, simultaneously active in Wright's work, and singled out by him as being of fundamental importance in his understanding of architecture.About the Author: Robert McCarter is a practicing architect and has been Ruth and Norman Moore Professor of Architecture at Washington University in St. Louis since 2007.
