Siegfried Bing

Henry van de Velde designed the interior of the gallery, while Louis Comfort Tiffany supplied stained glass.

During the gallery's most successful period, 1896–1902, Bing sold a great variety of artistic work, included fabrics designed by William Morris, glassware by Louis Comfort Tiffany, jewelry, paintings, ceramics, stained glass, and furniture of Art Nouveau style.

Bing dealt with customers ranging from private collectors to major museums, and helped to promote a global art market.

By this time Bing was the primary European dealer for the Rookwood Pottery Co. of Cincinnati and the Grueby Faience Company of Boston, as well as the wares of Tiffany.

[2] Bing advanced the careers of a wide range of artists, including Louis Bonnier, Frank Brangwyn, and Édouard Vuillard, the designers Eugène Gaillard, Edward Colonna, William Benson, and Georges de Feure, and the sculptor Constantin Meunier.
