Siegfried Bing (February 26, 1838 – September 6, 1905), often referenced erroneously as "Samuel Bing", was a German art dealer who lived in Paris as an adult, and who helped introduce Japanese art and artworks to the West and was a factor in the development of the Art Nouveau style during the late nineteenth century.
Bing was born in Hamburg, a member of a large family with diverse commercial interests. He relocated to France during 1854, to help manage the ceramics manufacturing business of Bing family in-laws, and resided in France for the remainder of his life. He became a naturalized French citizen during 1876. Bing married a second cousin, Johanna Baer, during July 1868. Their son Marcel Bing eventually became a business associate of his father's, as well as a jewelry designer of Art Nouveau style.
During 1873, on the death of his elder brother Michael, Siegfried Bing became the owner of Bing family enterprises in France. Bing developed a flourishing import-export business from the 1870s onward, working through several commercial entities with various partners and family members; he concentrated on the importation and sale of Japanese and other Asian objets d'art, though his business also exported French goods to Japan, working through a Yokohama office managed by his younger brother August. During December 1895 he opened his famous gallery, the Maison de l'Art Nouveau, which showed works of artists of what would become known as the Art Nouveau style. Henry van de Velde designed the interior of the gallery, while Louis Comfort Tiffany supplied stained glass. Bing's gallery featured entire rooms designed in the Art Nouveau style by his in-house designers.
During the gallery's most successful period, 1896–1902, Bing vended 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. His pavilion at the 1900 Paris World's Fair was especially notable. 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.
Bing advanced the careers of a wide range of artists, including Louis Bonnier, Frank Brangwyn, and Edouard Vuillard, the designers Eugène Gaillard, Edward Colonna, William Benson, and Georges de Feure, and the sculptor Constantin Meunier. Bing closed his gallery during 1904, a year before his death, when the fashion for Art Nouveau was already beginning to decrease.
Bing's activities were important, perhaps crucial, to the Japanese influence on Art Nouveau. He published a monthly journal, Le Japon Artistique, which began during 1888 and was collected in three volumes during 1891. The journal influenced people like Gustav Klimt.
Siegfried Bing has often been mis-named Samuel, perhaps in confusion with his brother, Samuel Otto Bing (1850–1905). (Siegfried consistently signed his name "S. Bing," facilitating the confusion.) Although Elias Bing, the American Biological Art Metal artist, produces Art-Nouveau inspired jewelry, there is not any family relationship.
