Léonce Rosenberg (12 September 1879, Paris – 31 July 1947, Neuilly-sur Seine), was an art historian, art collector, publisher and one of the most influential French art dealers of the 20th century. The son of an antique dealer Alexander Rosenberg and brother of the gallery owner Paul Rosenberg (21 rue de la Boétie, Paris), Léonce, a prominent gallery owner in Paris at the end of World War I, would become one of the world's major dealers of Modern art.
Leaving the family-owned gallery in 1910 Léonce opened his own business called Haute Epoque at 19 rue de La Baume, Paris. As an antiquarian Rosenberg began buying works by Cubist artists. By 1914 his collection included works by Pablo Picasso, Jean Metzinger, Albert Gleizes, Auguste Herbin, and Juan Gris. After serving in World War I (1916-1917) he pursued his interests and represented these and other artists, and by the end of the war opened a new show space, Galerie de L'Effort Moderne.
Léonce Rosenberg studied in London and Antwerp visiting galleries and museums in his free time. After returning to Paris he worked with his brother Paul in the family business. In 1906 Léonce and his brother inherited the family gallery on Avenue de l'Opéra which had been in existence for twenty years. His brother Paul was largely engaged in 19th- and early 20th-century art.
Léonce Rosenberg was an early advocate of Cubism, and would remain so throughout the 1920s and 1930s. He discovered the works of avant-garde artists in 1911 through the Salon des Indépendants, the art dealer Wilhelm Uhde, and in 1912 at the gallery of Daniel-Henry Kahnweiler.
At the outset of World War I many German nationals living in France had their possessions sequestered by the French state. As a German citizen Kahnweiler took refuge in Switzerland and ran out of funds. With his art collection the hand of the French government he could no longer support his artists. Following the advice of Max Jacob and André Level (known for his well informed art investments), Léonce Rosenberg began amassing his collection. Just before the outbreak of World War I Rosenberg purchased 15 Cubist works by Picasso for 12,000 FF. His collection would soon include 20 works by Picasso, 10 by Georges Braque, 5 by Juan Gris and 20 by Auguste Herbin.
Very quickly and despite his lack of experience Rosenberg became the official dealer of the Cubists purchasing works, in addition to those he already owned, by artist such as Jean Metzinger, Albert Gleizes, Fernand Léger, Joseph Csaky, Henry Laurens, Georges Valmier and Henri Hayden. Throughout World War I Rosenberg served as a moral and financial supporter of these artists. 'Without him' noted Max Jacob, 'a number of painters would be drivers or factory workers'
Picasso eventually switched over to his brother Paul Rosenberg's gallery, who would become his dealer Entre Deux Guerres.
Rosenberg volunteered for military service in 1915. He moved into a house at rue Marthe Édouard in Meudon near the military base, but also retained his Paris apartment at 22 rue Lavoisier and his Hôtel particulier 19 Rue de la Baume in the 8th arrondissement of Paris. During his periods of leave he continued to purchase Cubist works. From May, 1916, Rosenberg worked outside his unit as an English interpreter at the field headquarters of the Allied forces on the Somme front. During leave at the end of 1916 Rosenberg, through the intermediary of Juan Gris, went to Gino Severini's studio and bought a large painting of Woman Reading; possibly Severini's 1916 Femme lisant (Jeanne dans l’atelier; La lecture n. 1). The death of Umberto Boccioni during the month of August 1916 marked Severini's rupture from Futurism and his move closer to the Cubists.
Galerie de L'Effort Moderne
In March 1917, the second line of defense cleared Rosenberg's unit moved to Le Havre. In July of the same year Rosenberg returned to his old unit, now stationed at an airport in Nanterre. Closer to Paris, Rosenberg decided to reopen his gallery.
With the support given by Léonce Rosenberg, Cubism reemerged as a central issue for artists after four years of war. Rosenberg found himself financially ruined but exhibited the works he owned at his newly opened Galerie de L'Effort Moderne (also known as Galerie Léonce Rosenberg) at 19 Rue de la Baume. The gallery was open to all forms of Cubist and Abstract art. What followed would be a series of major one-man exhibitions. He also organized literary and musical events in his gallery.
The art collections of Kahnweiler and Uhde sequestered at the outset of WWI (which included works by Georges Braque, Raoul Dufy, Juan Gris, Auguste Herbin, Marie Laurencin, Fernand Léger, Jean Metzinger, Pablo Picasso, Jean Puy and Henri Rousseau) were sold by the government in a series of auctions at the Hôtel Drouot in 1921. Rosenberg had himself appointed as 'expert' for the sales.
From 1924 to 1927, Rosenberg made his activities known through his Bulletin de l'Effort moderne' (Éditions de l'effort moderne), a publication featuring writings and illustrations by contributors such as Léonce Rosenberg, Albert Gleizes, Piet Mondrian, Gino Severini.
In 1928, Rosenberg moved his personal collection to his apartment rue de Longchamp, Paris, and commissioned the artists he championed to realize decorative panels. (Giorgio de Chirico painted large panels for his living room).
A veritable center of activity and interest during the rise of modern art, the Galerie de L'Effort Moderne closed permanently in 1941, as a result of anti-Semitic laws.
