In addition to Proust and Antonio de La Gándara, the Princesse de Polignac's salon was frequented by Isadora Duncan, Jean Cocteau, Claude Monet, Sergei Diaghilev, and Colette. She helped Diaghilev with his Ballets Russes on multiple occasions and financially supported the company. She was also patron to many others, including Nadia Boulanger, Clara Haskil, Dinu Lipatti, Arthur Rubinstein, Vladimir Horowitz, Armande de Polignac, Ethel Smyth, Le Corbusier, Adela Maddison, the Ballets Russes, l'Opéra de Paris, and the Orchestre Symphonique de Paris. In addition to performing as pianist and organist in her own salon, she was an accomplished painter who exhibited in the Académie des Beaux-Arts. One canvas eventually appeared in the showcase of an art gallery, advertised as being a Manet.
