Léonce Rosenberg and the Idea of a Collective Cubism in the L’Effort Moderne Gallery during the Great World

Abstract

After the outbreak of the First World War and the forced exile of Daniel-Henry Kanhweiler, Léonce Rosenberg, Young art dealer decides to take over some of the artists previously hired by the German and some new personalities who came from other artistic styles. But the expectations of these artists, who saw in Rosenberg’s offer a way to survive during the war, would be far from the real aspirations of the dealer. With a commercial vision that, at times, does not coincide with that of the artists, and a strong temperament, relations would not always be easy and would blur interesting projects that would never come to light. Rosenberg’s convictions about the possibilities of a collective cubism, his demands in the production of certain pieces and his participation in Kahnweiler sales in the 1920s would lead to the diaspora of the Cubist group that cost so much effort to gather during the war.
