Berlin berliner secession
An association of artists founded in 1898 in Berlin, it was initiated by 65 young artists seeking an alternative to the conservative state-run Association of Berlin Artists. A factor in prompting the defection was the rejection of a painting by modernist Walter Leistikow. Max Liebermann was the first president of the Secession. The Cassirer Gallery in Berlin was a primary exhibition venue for the Berlin Secession painters that also included Lovis Corinth, Lyonel Feininger, Max Beckmann and Kathe Kollwitz.
