An updated edition of this classic survey of the origins of twentieth-century ideas in architecture and the applied arts. The turn of the nineteenth century saw an extraordinary flowering of invention in architecture and design, leading to the emergence of two contrasting styles: art nouveau and the International Style. Professor Nikolaus Pevsner brings clarity to this period of dynamic change by tracing the origins of twentieth-century ideas in architecture and the applied arts. Featuring a new foreword by the distinguished architectural historian Kenneth Frampton, The Sources of Modern Architecture and Design has now been updated with color illustrations throughout. 196 color illustrations
