This accessible and elegantly written book explores the meaning of modernism across a range of fields, including literature, architecture, design, science, technology, and visual arts. It offers a vivid portrait of the home as a site of transformation and change in the early decades of the twentieth century, leading to a profound revaluation of privacy, intimacy, cleanliness, originality, and other ideas that continue to define modernity. Rosner weaves her diverse sources into a single narrative that demonstrates that modernism was unexpectedly at its most radical in the seemingly cozy confines of the home.
