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|Société nationale des beaux-arts]] in 1895. In the same year, Bing opened a new gallery at [[Rue de Provence|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 [[Émile 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."{{Sfn|Bouillon|1985}}

The style was quickly noticed in neighbouring France. After visiting Horta's Hôtel Tassel, [[Hector Guimard]] built the [[Castel Béranger]], among the first Paris buildings in the new style, between 1895 and 1898.{{refn|group=nb|By some researchers Hôtel Jassedé (1893) is also attributed to Art Nouveau<ref>[https://art.nouveau.world/hector-guimard Hector Guimard] {{Webarchive|url= https://web.archive.org/web/20210225030004/https://art.nouveau.world/hector-guimard |date=25 February 2021}} – Art Nouveau World</ref>|note}} Parisians had been complaining of the monotony of the architecture of the boulevards built under [[Napoleon III]] by [[Georges-Eugène Haussmann]].  The Castel Beranger was a curious blend of Neo-Gothic and Art Nouveau, with curving [[whiplash (decorative art)|whiplash]] lines and natural forms. Guimard, a skilled publicist for his work,  declared: "What must be avoided at all cost is...the parallel and symmetry. Nature is the greatest builder of all,  and nature makes nothing that is parallel and nothing that is symmetric."{{Sfn|Fahr-Becker|2015|p=74}}

Parisians welcomed Guimard's original and picturesque style; the Castel Béranger was chosen as one of the best new façades in Paris, launching Guimard's career.  Guimard was given the commission to design the entrances for the new [[Paris Métro]] system, which brought the style to the attention of the millions of visitors to the city's 1900 {{lang|fr|[[Exposition Universelle (1900)|Exposition Universelle]]}}.<ref name="Gontar, Cybele 2006" />
