In 2004, the Senn-Foulds donation of 205 works (Delacroix, Corot, Courbet, Sisley, Pissarro, Monet, Guillaumin, Degas, Cross, Sérusier, Bonnard, Valloton, Derain, Matisse, Marquet…) from the collection of Olivier Senn, a merchant and friend of Marande, made the Musée Malraux the second Impressionist collection after Orsay.
In 2009, the same generous benefactor this time offered the collection of her father, Édouard Senn, a total of 67 works. Finally, in 2015, 17 new works from another branch of the Senn family joined the collections.
In the meantime, the circle of patrons contributed to the acquisition of a Friesz and a Marquet from the Fauvist period.
In 2019, in memory of her father, Florence Malraux bequeathed a painting by Georges Braque.
