CAHN, MARCELLE (1895–1981), cubist painter and member of the School of *Paris. Cahn was born in Strasbourg and studied in Berlin under Louis Corinth. She then moved to Paris where she was connected at first with the "Nabi" painters, but later came under the influence of Fernand Léger and the purist painter Amedie Ozenfant. From 1926 she painted in a rigorous and geometrical style, subordinating every element to the interests of composition. She associated closely with the cubists and took part in important exhibitions with Picasso, Braque, Léger, and Arp. From 1925 until 1930 she exhibited with the "Effort Moderne" group and from 1930 with the "Cercle et Carré" group.
