This study explored furniture and furniture designers in Art Nouveau which was called as Jugendstill in Germany. Jugendstill was developed on the center of Munchen, Darmstadt, and Berlin from the late 19th century to the early 20th century. And it was developed differently from Art Nouveau in the rest of European countries as the Rococo style and the Baroque style of Germany were done so. The furniture designers of Art Nouveau pronounced their use of decorative motifs from nature with birds, flowers, insects, fish, even landscape represented, but the designers in Jugendstill made the elaborate curvilinear design simply stylized and abstract: the design of Art Nouveau was seen as the superfluity of the ornament but the design of Jugendstill was seen as the simplified lines and restrain of the ornament. Hence, Jugendstill was deeply related with the scientific and rational thought of Germany, and then, it was based on the Deutscher Werkbund found by Hermann Muthesius.
