Although not as long-lasting as the Arts & Crafts moment, Art Nouveau was heavily influenced by the craftsmanship style, as well as Romanticism and Symbolism. The origin of the name Art Nouveau comes from an interior design gallery in Paris—Maison de l’Art Nouveau—that was an outlet for decorative creations by American Louis Comfort Tiffany, creator of the iconic Tiffany lamps. American architect Louis Henry Sullivan was also a proprietor of Art Nouveau; he frequently used plantlike Art Nouveau ironwork to decorate his buildings.
