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.

Hepburn famously shunned the Hollywood publicity machine and she refused to conform to society's expectations of women. She was outspoken, assertive, and athletic, and wore trousers before they were fashionable for women. She was briefly married as a young woman but thereafter lived independently. With her unconventional lifestyle and the independent characters she brought to the screen, Hepburn epitomized the "modern woman" in the 20th-century United States, and is remembered as an important cultural figure.
