Biography
Otto Hartmann was an Austrian active in the film industry during the early 20th century. Born on January 22, 1904 in Vienna, Hartmann appeared on screen in at least one credited role. In The Case of Colonel Redl [1931], Hartmann portrayed Stephan Dolan, a supporting character identified as Ulanenleutnant. This credit represents the only documented film appearance from available records.
The scope of Hartmann’s work remains limited based on verified sources. No additional film credits, stage performances, or other professional details have been confirmed. The available information suggests a brief engagement in cinema rather than a sustained career. The existing note identifying Hartmann as an actor and Gestapo informer provides context but does not alter the documented filmography.
