Passage: The Franco-German art dealer and publisher Siegfried Bing played a key role in publicizing the style. In 1891, he founded a magazine devoted to the art of Japan, which helped publicize Japonism in Europe. In 1892, he organized an exhibit of seven artists, among them Pierre Bonnard, Félix Vallotton, Édouard Vuillard, Toulouse-Lautrec and Eugène Grasset, which included both modern painting and decorative work. This exhibition was shown at the Société nationale des beaux-arts in 1895. In the same year, Bing opened a new gallery at 22 rue de Provence in Paris, the Maison de l'Art Nouveau, devoted to new works in both the fine and decorative arts. The interior and furniture of the gallery were designed by the Belgian architect Henry Van de Velde, one of the pioneers of Art Nouveau architecture. The Maison de l'Art Nouveau showed paintings by Georges Seurat, Paul Signac and Toulouse-Lautrec, glass from Louis Comfort Tiffany and Emile Gallé, jewellery by René Lalique, and posters by Aubrey Beardsley. The works shown there were not at all uniform in style. Bing wrote in 1902, "Art Nouveau, at the time of its creation, did not aspire in any way to have the honor of becoming a generic term. It was simply the name of a house opened as a rallying point for all the young and ardent artists impatient to show the modernity of their tendencies."
