For forty-five years, Winnaretta’s salon had become a very famous and influential place in the parisian society.
With her husband, Prince Edmond de Polignac, she wanted to create a place for artistic development. Their musical evenings were held more regularly with time and were inspired by the ones of Winnaretta’s old friend, Marguerite Baugnies, who had married sculptor René de Saint-Marceaux in 1892. Marcel Proust, who was often invited to the Polignacs’ concerts, mentioned their salon in his book A la Recherche du temps perdu.
As the reputation of the Polignacs' salon grew, the audience changed too. Many of the artists Winnaretta Singer had met at Saint-Marceaux’s salon became the regulars of her own: Debussy, d’Indy, Chausson, Colette, the painters John Singer Sargent and Claude Monet.
The Polignacs were also the owners of a mansion in Venice bought in 1900, where they invited numerous of their friends.
