This volume contains a collection of the key essays on and by Frank Lloyd Wright (1867-1959), one of the most influential and prolific architects of the 20th century. The individual essays focus on specific aspects of Wright's work, analyzing buildings and projects in order to explain the general principles of Wright's much-debated design methods. Included are previously published contributions from well-known historians and Wright scholars such as Kenneth Frampton, Colin Rowe, and Gwendolyn Wright, as well as newer commentary from the book's editor, Robert McCarter, an acknowledged Wright expert and author of Phaidon's Frank Lloyd Wright monograph. This volume brings together in one place decades of important scholarship on Wright and his architectural principles, making it an essential reader for students of architecture and enthusiasts of Wright's work.
