The style gained popularity through exposure at the Paris Exposition. French architects Hector Guimard, Jules Lavirotte, and Frantz Jourdain experimented with optics, transparency, motion, and point of view. Decorative artists, like Louis Majorelle, Emile Gallé, and Georges de Feure, contributed furniture, glass, and metalwork that integrated into the overall design, while jewelry, paintings, and poster design continued to use Art Nouveau techniques independent of architecture.
