Art Nouveau
Art Nouveau (in German, Jugendstil)--inspired by nature and featuring Tiffany lamps and similar works--gained favor around1900. Artists, artisans and architects drew on the art of Java (the island, not the language) to produce an art that aimed at the enlightened elite and nouveau riches. It lasted only a decade or so. Its adherents such as Munch and Toulouse-Lautrec found it more suitable to the industrial age than the classical Ecole des Beaux Arts.

In Vienna, there was a branch of Art Nouveau known as the Secession Movement. This movement would more fully integrate art and industry and eventually ushered in Art Deco.

Art Deco
Art Deco pushed the pendulum back; Art Nouveau had moved away from some folk art principles, and Art Deco restored them. It was characterized by classic motifs reduced to geometric stylizations, and featured artists such as Gustav Klimt (The Kiss). Together with Bauhaus, Art Deco achieved an integration of industry and art that the world had been seeking since the industrial age.
