Hans Walter Conrad Veidt (; 22 January 1893 – 3 April 1943) was a German film actor who attracted early attention for his roles in the films Different from the Others (1919), The Cabinet of Dr. Caligari (1920), and The Man Who Laughs (1928). After a successful career in German silent films, where he was one of the best-paid stars of UFA, he and his new Jewish wife Ilona Prager were forced to leave Germany in 1933 after the Nazis came to power. The couple settled in Britain, where he took British citizenship in 1939. He appeared in many British films, including The Thief of Bagdad (1940), before emigrating to the United States around 1941, which led to his being cast in what may be his best remembered role as Major Strasser in Casablanca (1942). This was his last film role to be released during Veidt's lifetime.
