The designer,Louis Comfort Tiffany, was famous for his stained glass lamps. He also designed jewellery.
Another designer from the Art Nouveau movement, Victor Horta, a Belgian architect known for wrought iron work, which was used and integrated into architectural designs.
A good example, is the Hotel Tassel Staircase in Brussels (1893). The design makes clear use of the whiplash line, which repeats the curvilinear lines in the floor decoration.
Elements of Design seen in ART NOUVEAU:
Line: whiplash line or serpentine line. Curvilinear and languid lines that are continuous and create stylised shapes.
Shape and Form: Organic curvilinear shapes that reflect the rhythm of the whiplash line.
Colour: For interiors they used subtle and subdued pastel colours, e.g. pinks, yellows and greens. Flat matt colour contained within curving outlines, generally used for poster illustrations, e.g. Posters by Mucha. √
Principles of Design seen in ART NOUVEAU:
Balance: predominantly asymmetrical.
Contrast: Large and small forms. Cool colours against warm ones.
Movement: the repetition of the whiplash line creates a sense of movement.
Subject matter: animals, birds and plants. Very stylised roses (Rennie Mackintosh), sunflowers, lilies and peacocks as well as sensuous female forms.
Products: textiles, ceramics, metal work, glassware, jewellery, furniture and architecture.
Materials: exotic materials, e.g. mother-of-pearl, lapis lazuli, ivory, iridescent coloured glass added to metal, ceramic jewellery ware and even furniture and wrought iron.
