(French: “New Art”). Art Nouveau was an international style in architecture, the decorative arts, graphic art and design that was popular between 1890 and 1910. It was typically inspired by natural forms, such as the sinuous curves of vines. Architects Henry van de Velde, Victor Horta, and Hector Guimard, illustrator Alphonse Mucha, and glass designers René Lalique and Louis Comfort Tiffany were important practitioners of the Art Nouveau style. Art Nouveau was known by several different names: Jugenstil in Germany, Stile Liberty in Italy, Nieuwekunst in the Netherlands, Modernismo in Spain, Modern Style and Glasgow Style in the United Kingdom.
