<\/p>\nMarianne Rosenberg grew up with art for \u201cbreakfast, lunch and dinner\u201d, she jokes. The Upper East Side dealer comes from a family of storied gallerists. Her great-grandfather, Alexandre Rosenberg, was a major art world figure in Paris in the late 19th century, acquiring works by artists like Paul C\u00e9zanne and Vincent van Gogh at a time when the market for Impressionist painting was still nascent. Anticipating a shift in taste that would later define Modern art history, his sons expanded that vision, but one son in particular, Paul Rosenberg, transformed the family name into a cornerstone of the 20th-century art market.<\/p>\n
With galleries in Paris and London, Paul cultivated relationships with artists that were both commercially astute and deeply personal. He represented figures like Henri Matisse, Fernand L\u00e9ger and Pablo Picasso, shaping their markets and institutional legacies, and becoming one of the most important dealers in the industry.<\/p>\n
War would interrupt Paul\u2019s trajectory when the family was forced to flee Nazi-occupied France in 1940. \u201cEverything was stolen,\u201d Marianne says. \u201cThat included things that were unimportant in the scheme of history, like pots and pans, as well as artwork, books and archival materials.\u201d Settling in New York, Paul re-established his gallery and was later joined by his son Alexandre P. Rosenberg in 1946. The two worked together until Paul\u2019s death in 1959, when Alexandre continued the business.<\/p>\n

Over the years, Alexandre (Marianne\u2019s father) built his own connections with artists, including Giacomo Manz\u00f9. Alexandre represented the Italian artist known for his bronze sculptures and reliefs, including the Door of Death (1961-64) for St Peter\u2019s Basilica in Vatican City, forming a close relationship until the dealer died in 1987. At that time, Paul Rosenberg & Co. closed.<\/p>\n
While she absorbed the art world through osmosis\u2014attending auctions and events with her mother and building a collection of her own\u2014Marianne spent the first part of her career as an attorney in international aviation finance law. It wasn\u2019t until 2015 that she started her gallery, Rosenberg & Co.<\/p>\n
\u201cThere was always a push and pull for me with the art world,\u201d Marianne says. \u201cI\u2019ve always been in it in ways, but I became very good at my job as a lawyer. At some point being on the hamster wheel was no longer fun, and the art world pulled stronger.\u201d<\/p>\n
Marianne has since continued her family\u2019s focus on Impressionist and Modern art, and she also works with contemporary artists. Like many families whose possessions were stolen by Nazis, she has also been trying to recover missing artworks, following in her grandfather and father\u2019s footsteps. Paul recovered around 300 works before his death and Alexandre was a lieutenant in the Free French Forces, helping to stop a train full of Nazis and looted artwork days after Paris was liberated.<\/p>\n
\u201cWe\u2019re very fortunate because my grandfather, Paul, was extraordinarily meticulous and kept records of every work that came through the gallery with an inventory number, measurements, even a little photo,\u201d Marianne says. The family was recently successful in the restitution of a painting by Camille Pissarro, but Marianne estimates there are still more than 50 works missing.<\/p>\n
Many of the records her grandfather kept are now in the Paul Rosenberg Archives at the Museum of Modern Art, a rich collection that offers insight into the inner workings of the art world in the first half of the 20th century and the lives of the famous figures Paul worked with.<\/p>\n
