The recently published Louis I. Kahn in Conversation: Interviews with John W. Cook and Heinrich Klotz, 1969–70 provides fresh insights into the philosophy and genius of one of America’s greatest twentieth-century architects. Transcribed from audio recordings of candid conversations that have never before been published in their entirety, these interviews with Kahn (1901–1974) were conducted by Heinrich Klotz, a young German architectural historian who was then a visiting professor at Yale University, and John W. Cook, who was teaching architecture at Yale Divinity School. The volume has been edited by Jules David Prown, Paul Mellon Professor Emeritus of the History of Art at Yale University and Senior Research Fellow at the Yale Center for British Art, and Karen E. Denavit, Information Analyst at the Center.
