The Section d'Or, also known as Groupe de Puteaux or Puteaux Group, was a collective of painters, sculptors, poets and critics associated with Cubism and Orphism. Based in the Parisian suburbs, the group held regular meetings at the home of the Duchamp brothers in Puteaux and at the studio of Albert Gleizes in Courbevoie. Active from 1911 to around 1914, members of the collective came to prominence in the wake of their controversial showing at the Salon des Indépendants in the spring of 1911. This showing by Albert Gleizes, Jean Metzinger, Robert Delaunay, Henri le Fauconnier, Fernand Léger and Marie Laurencin, created a scandal that brought Cubism to the attention of the general public for the first time.

Cubism is an early-20th-century avant-garde art movement that revolutionized European painting and sculpture, and inspired related artistic movements in music, literature, and architecture. In Cubist works of art, the subjects are analyzed, broken up, and reassembled in an abstract form—instead of depicting objects from a single perspective, the artist depicts the subject from multiple perspectives to represent the subject in a greater context. Cubism has been considered the most influential art movement of the 20th century. The term cubism is broadly associated with a variety of artworks produced in Paris or near Paris (Puteaux) during the 1910s and throughout the 1920s.
