Marianne Rosenberg, an Upper East Side dealer and descendant of the storied Rosenberg gallery dynasty, has opened a new exhibition titled "Giacomo Manzù: The Artist and his Dealer" at her gallery Rosenberg & Co., running until 27 June. The show features sculptures, works on paper, and archival letters that explore the decades-long relationship between Italian sculptor Giacomo Manzù and her father, Alexandre P. Rosenberg, who represented Manzù until his death in 1987. Marianne, who left a career in international aviation finance law to open her gallery in 2015, continues her family's focus on Impressionist and Modern art while also working with contemporary artists and pursuing restitution of artworks looted by the Nazis during World War II.
The exhibition matters because it not only revives the memory of Alexandre P. Rosenberg and his close ties with Manzù but also highlights the broader legacy of the Rosenberg family, which shaped the 20th-century art market through relationships with artists like Henri Matisse, Fernand Léger, and Pablo Picasso. The show coincides with ongoing efforts by Marianne to recover more than 50 missing artworks stolen from the family during the Nazi occupation, following the recent successful restitution of a Camille Pissarro painting. The Paul Rosenberg Archives at the Museum of Modern Art, which contain meticulous records of the family's dealings, provide invaluable insight into the inner workings of the early 20th-century art world and the lives of its most famous figures.
