Louis C. Tiffany was one of America's most acclaimed artists and businessmen working in the late nineteenth and early twentieth centuries. He directed an artistic empire in the design and creation of leaded-glass windows, lamps, blown glass vessels, objects of luxury, and mosaics--one of his most innovative expressions in the medium of glass. Tiffany's Glass Mosaics features essays from noted scholars and curators who, for the first time, investigate the breadth of mosaic production at the company from the 1880s through the 1930s. A detailed appendix lists all of the known public, ecclesiastical, and residential commissions executed by Tiffany's firm. The publication is richly illustrated with objects from major museums, libraries, and private collections in the United States and Europe. Many of these large-scale murals have never before been photographed or published.
