Mary Louise Brooks (November 14, 1906 – August 8, 1985), known professionally as Louise Brooks, was an American film actress and dancer during the 1920s and 1930s. She is noted as a flapper icon and sex symbol, and is famous for her bob hairstyle that she helped popularize during the prime of her career.
Brooks is best known as the lead in three feature films made in Europe: Pandora's Box (1929), Diary of a Lost Girl (1929), and Miss Europe (1930); the first two were made by G. W. Pabst. She starred in seventeen silent films and eight sound films before retiring in 1938. Brooks published her memoir, Lulu in Hollywood, in 1982; three years later she died of a heart attack at the age of 78.
