Katharine Houghton Hepburn (May 12, 1907 – June 29, 2003) was an American actress of film, stage, and television. Hepburn's career as a Hollywood leading lady spanned more than 60 years. Known for her headstrong independence and spirited personality, she cultivated a screen persona that matched this public image, and regularly played strong-willed, sophisticated women. Her work came in a range of genres, from screwball comedy to literary drama, and she received four Academy Awards for Best Actress—a record for any performer. In 1999, Hepburn was named by the American Film Institute the greatest female star of classic Hollywood cinema.
