I like this book so much: we used it for an art history course at Yale on art, architecture, and design from 1890-1940. Pevsner's goal, seemingly quite simple but really so complex, is to show the SOURCES of modernism, its origins. This is what the title suggests. Yet it seems he does so much more - he teaches, he gives things dignity, he makes clear intricate connections reaching across space, time, and place in architecture and the applied arts. Arts and Crafts, Art Nouveau, industrialism, the International Style - everything. Plus the illustrations are fitting and so beautiful. Pevsner gives mention to things often neglected - jewelry, ceramics, etc. It's a compact work, slim, beautiful, easy to read, and great to have as a reference.
