The Section d'Or exhibition took place in 1912.
The Salon de la Section d'Or opened at the Galerie La Boétie in Paris in October 1912. Organized by artists associated with the Puteaux Group, it became one of the most important public presentations of Cubism before the First World War. More than 200 works were displayed, offering viewers a broad survey of Cubist experimentation from roughly 1909 to 1912.
The exhibition helped present Cubism as a coherent artistic movement rather than a collection of unrelated experiments. Artists connected with it included Albert Gleizes, Jean Metzinger, Fernand Léger, Juan Gris, Alexander Archipenko, Francis Picabia and the Duchamp brothers. Guillaume Apollinaire gave the opening address, and Gleizes and Metzinger's book Du “Cubisme” appeared in the same year.
A common mix-up is confusing the 1912 exhibition with later Section d'Or shows held in 1920 and 1925. The name also refers to the wider artistic group, which was active from about 1911 to 1914, not only to the landmark 1912 exhibition.
