This year marks the 100th anniversary of an event that changed Paris—and fine art—forever: the 1925 International Exhibition of Modern Decorative and Industrial Arts. Designers and artists such as Josef Hoffmann, Robert Mallet-Stevens, and Jean and Joël Martel unveiled works bold and glamorous—sculptures, paintings, and furniture that shared a sleek geometry and symmetry. The show signaled the advent of Art Deco. “The art of 1900 was the art of the realm of fantasy,” the painter Charles Dufresne observed. “That of 1925 is the art of reason.” This exhibition celebrates the centennial with almost a thousand works of sculptural furniture, precious jewelry, objets d’art, drawings, posters, and fashion pieces. —Elena Clavarino
