American designer. Son of the silversmith Charles Lewis Tiffany, he trained as a painter in the 1860s with the artist Samuel Coleman. Tiffany began working with glass in 1873. In 1879 he established Associated Artists, designing opulent interiors for wealthy East Coast families. He set up Tiffany Glass and Decorating Co (later Tiffany Studios) in 1892, and in 1894 registered his Favrile glass patent. Tiffany had close ties with European Art Nouveau: he made a series of windows designed by leading French artists in 1895, and his lamps and glassware appeared at the Paris gallery of Siegfried Bing three years later. His signature leaded glass lamps were first shown in 1899. In 1902 he became design director of the family silver firm Tiffany & Co. He turned to jewellery around 1904.
