A fascinating treasury of drawings and plans from one of the 20th century s greatest architects, commented to open unprecedented insight into his design process. The importance of a drawing is immense, because it s the architect s language, said the architect Louis Kahn to his masterclass in 1967. While Kahn s built work has been extensively studied, this publication chooses instead to focus on his drawings as primary sources of insight into his architectural intelligence and imagination. Lavishly illustrated with over 600 high-quality reproductions of work by Kahn and his associates, incisively presented by a group of acclaimed architectural experts, The Importance of a Drawing is a deep immersion into Kahn s work and his design process. A testament to Kahn s masterly craft, this volume also makes a provocative primer on architectural representation by posing timely questions on how architects use drawings to see, learn, conjecture, and reveal. Destined to become a standard reference on Kahn, this book is an essential addition to the libraries of established designers as well as students of architecture. The result of years of extensive research, The Importance of a Drawing contains original contributions and historical texts from Michael Benedikt, Michael B. Cadwell, Louis I. Kahn, Nathaniel Kahn, Sue Ann Kahn, David Leatherbarrow, Michael J. Lewis, Robert McCarter, Michael Merrill, Marshall D. Meyers, Jane Murphy, Harriet Pattison, Gina Pollara, Colin Rowe, David Van Zanten, Richard Wesley, and William Whitaker.
