[clarification needed] The main pavilion, an 1830s hôtel particulier, was the Paris base of the Dutch-born painter Ary Scheffer, one of the prominent artists of the time, close to King Louis-Philippe and his family.
For decades, Scheffer and his daughter hosted Friday-evening salons, among the most famous in La Nouvelle Athènes.
George Sand used to come as a neighbour with Frédéric Chopin, meeting Eugène Delacroix, Jean-Auguste-Dominique Ingres, Alphonse de Lamartine, Franz Liszt, Gioacchino Rossini and singer Pauline Viardot.
The Museum displays on the first floor numerous mementos of the romantic literary figure George Sand, including family portraits, household possessions, pieces of jewelry and memorabilia including plaster casts by Clésinger of the writer's sensuous right arm and Chopin's delicate left hand, plus a number of her own unique and rare watercolours called "dendrites".
The Museum also displays several portraits and material related to the famous scholar and writer Ernest Renan who had married Ary Scheffer's niece.
