Known as Jugendstil in Germany, Sezessionstil in Austria, Modernista in Spain, and Stile Liberty or Stile Floreale in Italy, Art Nouveau has become the general term applied to a highly varied movement that was European-centred but internationally current at the end of the century.
Art Nouveau architects gave idiosyncratic expression to many of the themes that had preoccupied the 19th century, ranging from Viollet-le-Duc's call for structural honesty to Sullivan's call foran organic architecture.

Decorative exploitation of the architectural surface with flexible, S-shaped linear ornament, commonly called whiplash or eel styles,was indulged in by the Jugendstil and Sezessionstil architects. The Studio Elvira at Munich (1897-98) by August Endell and Otto Wagner's Majolika Haus at Vienna (c. 1898) are two of the more significant examples of this German and Austrian use of line.
