One of the most significant architects of the last century, Louis Kahn continues to provoke and inspire. This book explores Kahn through the architectural models that were integral to his design practice. To create his work, Kahn called upon a broad repertoire of architectural techniques, tools and finesses - some derived from the École des Beaux-Arts, others absorbed through key collaborators such as Anne Tyng, Robert Venturi and Isamu Noguchi. The models of Kahn and of those three collaborators are studied to question their roles as design tools, as bearers of ideas and as shapers of thought. With richly illustrated texts, visual essays and new images by photographer Raymond Meier, the publication is timely not only for what it reveals about the architect, but as a means to reflect on how we continue to think with objects in our making of architecture.
