The Art Nouveau movement was known as Jugendstil ("Youth Style") in Germany, and in Austria the designers of the Vienna Secession group — notably Koloman Moser, Josef Hoffmann and Joseph Maria Olbrich — produced a relatively austere iteration of the Art Nouveau style, which mixed curving and geometric elements. Like a mayfly, Art Nouveau was short-lived.

But as the designs on 1stDibs demonstrate, Art Nouveau retains its power to fascinate and seduce.
