Few architects shaped the course of architectural history as dramatically as Frank Lloyd Wright. While Wright has long been the focus of scholarly debate, among his other many accomplishments during his long career he was also the author of key essays on design that have influenced generations of architects. This volume brings together the most important essays on and by Wright, providing both an illuminating study of one of the key figures of the 20th century, as well as an overview of the very principles that are at the foundation of great architecture. The editor of this volume, Robert McCarter, poured through all of the important scholarly work on the subject of Frank Lloyd Wright to select the highlights in research and reading. Each essay is illustrated with archival material.
