Berthe Weill (Paris, 1865 - 1951) was a French art dealer and gallery owner who played a key role in creating the twentieth-century art market and promoting the Parisian avant-garde. She is credited with selling the first works by Pablo Picasso and Henri Matisse and organizing the only solo exhibition of Amedeo Modigliani. The exhibition at the Musée de l'Orangerie in Paris aims to tell her story and that of her famous gallery, which opened its doors at 25 Rue Victor-Massé in the Pigalle district in 1901 and which for 40 years was a driving force for the whole of Europe. Around one hundred paintings, sculptures, drawings, prints and jewels on display at the Parisian museum will try to recall the fervent activity of the B. Weill Gallery with masterpieces signed by Pablo Picasso, Henri Matisse, Diego Rivera, Amedeo Modigliani, Emilie Charmy, Pierre Girieud and Otto Freundlich.
