Although she is much less known than her well-established competitors like Ambroise Vollard, Daniel-Henry Kahnweiler and Paul Rosenberg, she may be credited with producing the first sales in Paris for Pablo Picasso[2]: 26 and Henri Matisse[2]: 26 and with providing Amedeo Modigliani with the only solo exhibition in his lifetime.
The impressive list of artists who made their way through her gallery and into the canon of modern art continues with names such as Raoul Dufy, André Derain, Maurice de Vlaminck, Diego Rivera, Georges Braque, Kees van Dongen, Maurice Utrillo, Pablo Picasso, François Zdenek Eberl and Jean Metzinger.
[6]: 11 In 2009, her memoirs (1933) were republished[1] and a compilation of her gallery exhibitions;[6] in 2011, the first study dedicated to her life and dealership was published by leading Weill scholar Marianne Le Morvan.
