The New Objectivity was a movement in German art that arose during the 1920s as a reaction against expressionism. The term was coined by Gustav Friedrich Hartlaub, the director of the Kunsthalle in Mannheim, who used it as the title of an art exhibition staged in 1925 to showcase artists who were working in a post-expressionist spirit. As these artists—who included Max Beckmann, Otto Dix, Adolf Dietrich, George Grosz, Christian Schad, Rudolf Schlichter, Georg Scholz and Jeanne Mammen—rejected the self-involvement and romantic longings of the expressionists, Weimar intellectuals in general made a call to arms for public collaboration, engagement, and rejection of romantic idealism.
