Mercedes de Acosta (1893 – 1968) was an American poet, playwright, and novelist. She was professionally unsuccessful but is known for her many lesbian affairs with famous Broadway and Hollywood personalities and numerous friendships with prominent artists of the period. De Acosta was involved in numerous lesbian relationships with Broadway's and Hollywood's elite and she did not attempt to hide her sexuality; her uncloseted existence was very rare and daring in her generation. In 1916 she began an affair with actress Alla Nazimova and later with dancer Isadora Duncan. Shortly after marrying Abram Poole in 1920, de Acosta became involved in a five-year relationship with actress Eva Le Gallienne. Over the next decade she was involved with several famous actresses and dancers including Greta Garbo, Marlene Dietrich, Ona Munson, and Russian ballerina Tamara Platonovna Karsavina. Additional unsubstantiated rumors include affairs with Pola Negri, Eleonora Duse, Katherine Cornell, and Alice B. Toklas. In 1960, when de Acosta was seriously ill with a brain tumor and in need of money, she published her memoir, "Here Lies the Heart." In it are recounted the off stage life and lifestyles of many of the iconic figures of Hollywood in from the 1920's to 1940's.
