In 1921 Dietrich enrolled in Max Reinhardt’s Deutsche Theaterschule, and she eventually joined Reinhardt’s theatre company. In 1923 she attracted the attention of Rudolf Sieber, a casting director at UFA film studios, who began casting her in small film roles. She and Sieber married the following year, and, after the birth of their daughter, Maria, Dietrich returned to work on the stage and in films. Although they did not divorce for decades, the couple separated in 1929.
