This book explores the work of those artists who attempted to keep alive the expanded possibilities opened up by Cubism in Paris between 1911 and 1914. This little community of artists refused to accept that recording the war or producing propaganda was their duty. Instead, they kept faith in their independence as individuals as this war of machines threatened to rob every front-line soldier of his humanity and to draw the globe into unprecedented conflict. The vast majority of fit young Frenchmen were mobilized, so those artists left behind in Paris were either foreign or too old or unfit for combat. Pablo Picasso, then known as the inventor of Cubism, remained a prominent figure, alongside his fellow Spaniards Juan Gris and Maria Blanchard, the Mexican Diego Rivera, the Italian Gino Severini, the Lithuanian sculptor Jacques Lipchitz and the French painters Georges Braque, Henri Laurens, Fernand Leger and Henri Matisse. One focus of this book is the sheer diversity of the work produced by these artists; another is the move made by most of them toward a more structured, architectural Cubism, especially from 1917, which could be taken as reparation against the destructive forces that seemed to have taken over the whole world.

The history of modernism has generally been written as a story of artists and their creations alongside the collectors, gallerists, and curators who supported them. This is especially true of Cubism, where the received narrative centers on a tightly circumscribed group of artists and agents connected to the dealer Daniel-Henry Kahnweiler. Léonce Rosenberg’s Cubism shakes up the canon, revealing its artificial nature and pointing to a different, more inclusive understanding of the development of Cubism. Kahnweiler’s Cubism was narrowly focused. In contrast, Giovanni Casini shows us, the influential art dealer Léonce Rosenberg bought virtually any piece that could be labeled “Cubist� and proposed a radically different understanding of the movement. At Rosenberg’s Galerie L’Effort Moderne in Paris, artists such as Joseph Csáky, Auguste Herbin, Jean Metzinger, Diego Rivera, Gino Severini, and Georges Valmier were accorded the same treatment as Pablo Picasso or Georges Braque. In this book, Casini considers Rosenberg’s contribution to the history of Cubism, reflecting on the ways in which artistic movements are manufactured—and interpretive paradigms adopted. Deftly weaving biography with a scholarly analysis built on extensive archival research, Léonce Rosenberg’s Cubism is a fresh look at the history of interwar modernism and the definitive study of a figure who has been unjustly sidelined in the history of art. It will be compulsory reading for scholars of Cubism and Modernism.
