Winnaretta Singer, American philanthropist (d. 1943)

Winnaretta Singer, Princesse Edmond de Polignac (8 January 1865 – 26 November 1943) was an American-born heir to the Singer sewing machine fortune. She used this to fund a wide range of causes, notably a musical salon where her protégés included Debussy and Ravel, and numerous public health projects in Paris, where she lived most of her life. Singer entered into two marriages that were unconsummated, and openly enjoyed many high-profile relationships with women.
