Lewis Mumford was one of America's leading cultural critics and international authorities on architecture and urbanism. The author of more than 20 books, his writings bridged the seemingly disparate disciplines of architecture, technology, literary criticism, biography, sociology, and philosophy. Sidewalk Critic collects over 50 of Lewis Mumford's writings from 1931 to 1940 which focus on the New York metropolitan area and provide an unusual glimpse into one of the most formative decades in the city's history.
