Ozenfant, Amédée (ämādāˈ ōzäNfäNˈ) [key], 1886–1966, French art theorist and painter. He criticized the cubists after 1912 for creating a merely decorative art form. Ozenfant advocated a disciplined geometry known as purism. With Le Corbusier he wrote Après le cubisme (1918) and La peinture moderne (1927). His painting The Vases is in the Museum of Modern Art, New York City. Ozenfant's book Foundations of Modern Art (1931) is well-known.
