German film director whose films were among the most artistically successful of the 1920s. Pabst's films are marked by social and political concerns, deep psychological insight, memorable female protagonists, and human conflicts with culture and society. He is also noted for his mastery of film editing.

Pabst was educated in Vienna and at age 20 began a career as a stage actor in Zürich. He performed in Berlin, New York City, and Salzburg, Austria, before turning to the cinema. Pabst's first film was Der Schatz (1923; The Treasure), about the passions aroused during a search for hidden treasure. His first successful film as a director was Die freudlose Gasse (1925; The Joyless Street), which became internationally famous as a grimly authentic portrayal of life in inflation-ridden postwar Vienna. His second successful film was Geheimnisse einer Seele (1926; Secrets of a Soul), a realistic consideration of psychoanalysis that recalls Expressionist themes in its detailed examination of a disturbed consciousness. Die Liebe der Jeanne Ney (1927; The Love of Jeanne Ney) incorporates documentary shots to heighten the realism of its postwar setting. These three films sealed Pabst's international reputation.

His films of the late 1920s and '30s contain a stronger emphasis on the interrelationship between social conditions and the individual. Outstanding are Abwege (1928; Crisis), Die Büchse der Pandora (1929; Pandora's Box), and Das Tagebuch einer Verlorenen (1929; Diary of a Lost Girl). The last two films are particularly notable for the performances of actress Louise Brooks (Brooks, Louise), who epitomized Pabst's ideal of feminine eroticism. In the early 1930s Pabst took up a left-wing viewpoint in such films as Westfront 1918 (1930), a realistic portrayal of trench warfare, Die Dreigroschenoper (1931; The Threepenny Opera), and Kameradschaft (1931; Comradeship), in which the virtues of international cooperation are extolled via a mine disaster met by the combined rescue efforts of French and German workers.

By the mid-1930s the overall quality of Pabst's films was declining. He moved to Paris and directed Don Quixote (1933), a ponderous three-language version of the novel, as well as several melodramas. At the outbreak of World War II he returned to Germany and reluctantly directed historical films imposed upon him by the Nazi regime. These included Komödianten (1941; Comedians), about the great German actress-manager of the 18th century Caroline Neuber (Neuber, Caroline), and Paracelsus (1943), a biography of the revolutionary 16th-century German physician. Though Pabst later professed to despise these films, his collaboration with the Third Reich impeded his career. He moved to Vienna and made Der Prozess (1948; The Trial), a strong indictment of anti-Semitism that helped restore his image. His most outstanding postwar films were also his strongest anti-Nazi statements: Es geschah am 20. Juli (1955; “It Happened on July 20”; released in English as Jackboot Mutiny), about the failed attempt to assassinate Hitler; and Der letzte Akt (1955; The Last Act, or The Last Ten Days), a re-creation of the final days of the Hitler regime.
