Marion Davies (born Marion Cecilia Douras; January 3, 1897 – September 22, 1961) was an American actress, producer, screenwriter, and philanthropist. Educated in a religious convent, Davies left the school to pursue a career as a chorus girl. As a teenager, she appeared in several Broadway musicals and one film, Runaway Romany (1917). She soon became a featured performer in the Ziegfeld Follies. While performing in the 1916 Follies, the nineteen-year-old Marion met the fifty-three-year-old newspaper tycoon, William Randolph Hearst, and became his mistress. Hearst took over management of Davies' career and promoted her as a film actress.
Hearst financed Davies’ pictures and promoted her career extensively in his newspapers and Hearst newsreels. He founded Cosmopolitan Pictures to produce her films. By 1924, Davies was the number one female box office star in Hollywood because of the popularity of When Knighthood Was in Flower and Little Old New York, which were among the biggest box-office hits of their respective years. During the zenith of the Jazz Age, Davies became renowned as the hostess of lavish soirees for Hollywood actors and political elites. However, in 1924, her name became linked with scandal when film producer Thomas Ince died at a party aboard Hearst's yacht.
