Proust, Claude Monet, Pierre-Auguste Renoir, Odilon Redon, Paul Signac, Claude Debussy, Stéphane Mallarmé, and André Gide. The entertainment was lavish. Henri de Toulouse-Lautrec enjoyed playing bartender at Natanson's parties, and became known for serving a potent cocktail— a drink of colorful layered liqueurs dubbed the Pousse-Café. All were mesmerized by the charm and youth of their hostess. In 1889, Natanson debuted La Revue blanche, a periodical committed to nurturing new talent and showcasing the work of the post-Impressionists, Les Nabis. Sert became the muse and symbol of La Revue blanche, appearing in advertising posters created by Toulouse-Lautrec, Édouard Vuillard and Pierre Bonnard. A portrait of Sert by Renoir is now in the Tate Gallery. Marcel Proust used Sert as the prototype for the characters of "Princess Yourbeletieff" and "Madame Verdurin" in his roman à clef À la recherche du temps perdu, (Remembrance of Things Past).

This period began her reign and fame as cultural arbiter, which lasted more than thirty years. Writer Paul Morand described her as a "collector of geniuses, all of them in love with her." It was recognized that "you had to be gifted before Misia wanted to know you." It was in her salon, while listening to Erik Satie at the piano playing his iconic composition Trois morceaux en forme de poire, that the assembled guests were informed that World War
