The discovery of light-sensitive chemicals in mid-nineteenth-century Europe carried large implications--for scientists, technicians, astronomers, and for the businesspeople who soon made family portraiture standard tabletop fare in middle-class homes. In this book, M. Susan Barger and William B. White trace the daguerreotype's origins and development. They then proceed to discuss what researchers in this century have learned about the chemistry of the daguerreotype. They also address practical curatorial issues, describing how to restore and preserve the artifacts themselves. Richly illustrated, this book also provides a detailed technical study of the daguerreotype process. Paperback, 252 pages.
