Hector Guimard, in full Hector-Germain Guimard, (born March 10, 1867, Lyon, France—died May 20, 1942, New York, New York, U.S.), architect, decorator, and furniture designer, probably the best-known French representative of Art Nouveau.

Art Nouveau, ornamental style of art that flourished between about 1890 and 1910 throughout Europe and the United States. Art Nouveau is characterized by its use of a long, sinuous, organic line and was employed most often in architecture, interior design, jewelry and glass design, posters, and illustration.

René Lalique, (born April 6, 1860, Ay, France—died May 5, 1945, Paris), French jeweler during the early 20th century whose designs in jewelry and glass contributed significantly to the Art Nouveau movement at the turn of the century.

French glassware and jewelry designer René Lalique (1860–1945) is recognized as one of the late nineteenth and early twentieth centuries' finest creators of Art Deco and Art Nouveau decorative items. Lalique's glassware was both stylistically and technologically innovative, leading to great success for the designer both in personal and architectural glass products. Today, Lalique is particularly remembered for his decorative glass, such as vases and bowls; the Lalique Company continues to produce art glass and jewelry to this day.
