A Visionary Art Dealer: Léonce Rosenberg

Lėonce Rosenberg at his Gallery L'Effort Moderne in Paris.

Léonce Rosenberg was one of the most important French art dealers of the 20th century. He supported Cubist artists right after the Great War, when most other dealers would not touch Cubism. The artist and poet Max Jacob is known to have said that without Rosenberg, a number of painters would have ended up as drivers or factory workers. Rosenberg strengthened his relationship with Picasso by buying Harlequin in 1918. However, it is not to his support of Cubism that I want to draw your attention, but rather to another aspect of his life. In 1928, Rosenberg embarked on a colossal, ambitious project: decorating the apartment he had bought at 75, Rue de Longchamp in Paris. The vision he brought to this project was truly staggering. Although short-lived, this project remains an important, if lesser-known, landmark in European art history between the two World Wars.

The spacious apartment in the upscale 16th arrondissement of Paris was intended as the living quarters for Rosenberg, his wife, and their three daughters. A group of artists—including Giorgio de Chirico, Fernand Léger, Francis Picabia, Gino Severini, and Max Ernst—was commissioned to decorate the rooms, which would also feature a curated selection of antiques and contemporary furniture. Right from the start, Rosenberg decided on the principle of assigning each room to a single artist. This was quite a feat in itself, but what made the project truly unique was the art itself: collectively, it stood as a bold repudiation of Fascist and Nazi propaganda, with each artist proclaiming that modern art was here to stay.

Giorgio de Chirico’s Gladiators series hung in the reception hall, with the painting The Combat positioned at the center.

Fascism idealized the classical concept of the male nude and Ancient Rome. The Combat by Giorgio de Chirico—one of eleven works that comprised The Gladiators series—at first glance looks like a traditional battlefield scene filled with horses and warriors. However, de Chirico turns these figures into a far cry from the heroic ideal: clumsy bodies with flabby musculature, unwarlike expressions, and an utter ineptitude at combat. They simply seem to tumble over one another—a masterclass in irony and satire.

The Tightrope Walker by Gino Severini

Gino Severini’s works were intended for the bedroom of Jacqueline, Léonce’s daughter.

The works of the Futurist, Cubist painter Gino Severini continue the juxtaposition of a classical theme—ancient ruins—with commedia dell’arte characters. These ruins may once have been the heart of a powerful empire, but here they serve merely as meaningless backdrops or, at best, settings for lighthearted recreation.

The panels Nudes in a Landscape by Manuel Rendón Seminario were created for Léonce Rosenberg’s bedroom.

Manuel Rendón Seminario, a lesser-known artist of Ecuadorian origin, produced a series of nudes for Rosenberg’s home. Set in a somewhat surrealistic landscape filled with simplified geometric shapes and vibrant colors, these figures revisit the story of Adam and Eve.

The Last Judgement by Jean Viollier

The Swiss painter Jean Viollier contributed a triptych consisting of Ascent to Paradise on the left and Descent into Hell on the right. The Last Judgment, the central panel, incorporates religious iconography with jarring contemporary elements like machinery and ladders. The figure of God is surrounded by naked apostles or saints—one of whom holds a dagger—alongside an angel riding an enormous black bird with a lighted torch in its claw, a small man climbing a staircase, industrial machinery, and what looks like a figure hoping to be rescued from the clutches of a demonic angel. All of these elements tend to alarm rather than reassure, a feeling only reinforced by the palette's acidic colors.

Pavonia by Francis Picabia

Rubi by Francis Picabia

Francis Picabia’s Transparencies paintings, with different images layered on top of one another, draw inspiration from human forms as well as the animal and plant worlds, uniting them all into a multi-layered puzzle. These works evoke Classicism and Botticelli’s Madonnas. Even if their meaning might escape us, we are enthralled by the esoteric beauty of these remarkably modern creations. Gertrude Stein, a friend of Picabia, praised his multi-dimensional paintings for going beyond the flat surface.

The City of Promises by Alberto Savinio. Francis Picabia and Alberto Savinio’s works were intended to decorate the bedrooms of Madame Rosenberg and her daughters.

Alberto Savinio’s work displayed in the Rosenberg apartment reflected a different aesthetic than that of his brother, Giorgio de Chirico. "Alberto Savinio" was a pseudonym adopted specifically so the artist's output would not stand in the shadow of his famous sibling. In The City of Promises, a stack of wobbly edifices—many resembling tombstones—is held together and solidified by fluid highlights that give the city an otherworldly, dreamlike quality.

Flowers of Seashells by Max Ernst

The exploration of layering continues with the paintings Max Ernst created for Rosenberg’s residence. Ernst used the frottage technique—layering different colors on top of one another and then scraping them back to reveal luminous hues that seem to shift when viewed from different angles. Flowers of Seashells, a hybrid of floral, mineral, and marine elements, features surreal flowers floating against a colorful background.

Four Seasons by Fernand Léger. The Four Seasons panels were hung in the entrance hall.

Léonce Rosenberg commissioned Fernand Léger to create four panels depicting the four seasons, even going so far as to suggest specific details for each panel. In these compositions, everyday objects—grapes, leaves, an ear of wheat, a swallow—float against abstract backgrounds, celebrating everyday life.

Unfortunately, Léonce Rosenberg did not anticipate the global financial crisis of 1929. Within a few years, he was forced to find smaller lodgings, and the artworks in the apartment were sold off in stages. He never fully recovered from this economic collapse, though he managed to keep his gallery, L’Effort Moderne, running for a time. In 1941, he was forced to close its doors permanently. As a Jew and a supporter of so-called “degenerate art,” Rosenberg had to flee Nazi-occupied Paris. In 1947, Rosenberg died penniless and heartbroken in Neuilly-sur-Seine, France. To this day, a portion of the collection from 75, Rue de Longchamp remains missing.
