The name 'Art Nouveau' derived from the name of a shop in Paris, Maison de l'Art Nouveau, at the time run by Siegfried Bing, that showcased objects that followed this approach to design.

Art Nouveau was a movement that greatly influenced many artists and designers and later progressed onto the De Stijl movement (from 1880-1905) and the German Bauhaus school (early 1920's-1930's).

The Hermitage Amsterdam will be dedicating its eighth exhibition to the beauties of Art Nouveau. The objects produced within this movement are the highlights of the Western decorative arts collection in the Hermitage in St Petersburg. This collection of Art Nouveau has not previously been on show in the Netherlands. Amongst the major works are the gifts to the last tsars made by the glassmakers Émile Gallé and the Daum brothers; works by René Lalique and Carl Fabergé will also be included.
