In 1878, after establishing himself as an antiques dealer in Paris, Marianne Rosenberg's great-grandfather, Alexandre Rosenberg (1842–1913) bought works by Paul Cézanne, Edouard Manet, Vincent Van Gogh, and the Impressionists. Following in Alexandre's footsteps, his two sons entered the Paris art market as partners, later founding separate galleries. Marianne Rosenberg's grandfather Paul (1881–1959) opened his gallery at 21 rue la Boétie in 1908, and her great-uncle Léonce (1878–1947) followed suit in 1910 with his Galerie de l'Effort Moderne.


Paul Rosenberg’s space at 21 rue la Boétie flourished in the 1920s and 1930s. During this time, the dealer exclusively represented numerous artists, including Georges Braque, Marie Laurencin, Fernand Léger, André Masson, Henri Matisse, and Pablo Picasso, whom Rosenberg represented for over two decades. In 1935 he opened a second space in London to attract a growing international audience. Between these two locations, Rosenberg became known as one of the most important sources of nineteenth and twentieth-century French painting, placing works in museums in both Europe and the U.S.


In 1940, with the onset of World War II, Paul Rosenberg moved to New York where he continued Paul Rosenberg & Co. at a gallery space on East 57th Street, and later moved the gallery to East 79th Street. Paul’s son, and Marianne Rosenberg's father, Alexandre P. Rosenberg (1921–1987) remained in Europe to fight with the Free French Forces. In 1946, Alexandre joined the New York gallery to continue his father’s legacy as a dealer and collector, and became the founding President of the Art Dealers Association of America in 1962.
