Marlene Dietrich was a German actress and singer. Dietrich remained popular throughout her long career by continually re-inventing herself. In 1920s Berlin, she acted on the stage and in silent films. Her performance as Lola-Lola in The Blue Angel, directed by Josef von Sternberg, brought her international fame and a contract with Paramount Pictures in the US. Hollywood films such as Shanghai Express and Desire capitalized on her glamour and exotic looks, cementing her stardom and making her one of the highest paid actresses of the era. Dietrich became a US citizen in 1937; during World War II, she was a high-profile front-line entertainer. Although she still made occasional films in the post-war years, Dietrich spent most of the 1950s through the 1970s touring the world as a successful show performer. In 1999, the American Film Institute named Dietrich the ninth greatest female star of all time.
