Heiress to the singer sewing machine empire, Winaretta Singer was a lifelong patron of the arts who hosted a salon in Paris from the late 1800s up through 1939, hosting artists including Claude Debussy, Igor Stravinsky, Cole Porter, Kurt Weill, Isadora Duncan, Colette, Claude Monet, Jean Cocteau, and Marcel Proust.
Beyond helping to fund the arts with donations to the Paris opera and symphony, she partnered with Marie Curie to send mobile radiology units — in limousines — to the front during World War I.
Singer was married twice to men, once to a European aristocrat with whom she did not consummate the marriage, and again to a prince, Edmond de Polignac, who was reportedly gay. Among her female lovers were painter Romaine Brooks, novelist Violet Trefusis, and composer-conductor Ethyl Smith.
She died in 1943.
