Originally published in 1929, this book demonstrates the architecture of the 1920s as the product of over a century of architectural development, despite the visual evidence that seemed to indicate that it had made a radical break with the past. Modern Architecture crystallised the history and theories behind the international style for an American audience. Hitchcock was only 27 at the time, and Modern Architecture was his first book; yet it would substantially reshape the way subsequent generations would view modern architecture and its history. Furthermore, Modern Architecture is the book that would establish Henry-Russell Hitchcock as a pre-eminent American historian of modern architecture.
