Gernot Bock-Stieber (born August 25, 1892 – December 7, 1943) was an Austrian film director, screenwriter and documentary filmmaker.
Born in Bad Gleichenberg, Styria, Austria-Hungary, Bock-Stieber attended the conservatory in Vienna after graduating from high school and trained as an actor with Josef Kainz.
Even before the outbreak of the First World War, Bock-Stieber had completed training as a photographer and movie camera operator.
Based in Germany since 1909, he played mainly in theaters in cities in the Rhine region including Cologne, Bonn and Düsseldorf, and finally went to Berlin, where he appeared as an actor at the Luisen Theater and was hired by the film production company Duskes Film as an assistant director.
The screenplay for his productions was regularly written by Ada van Roon, Bock-Stieber's wife since 1917.
