Louis Comfort Tiffany

Art glass, New York. Tiffany, son of the jewellery firm's founder, ran his own glass and decorating studios from the late 1870s and developed opalescent and iridescent glass for windows and lamps. Much of the design and selection of glass was done by a women's department led by Clara Driscoll, whose role was recognised only decades later. The studios combined artistic direction with workshop production on a large scale.
