The Great King
1956
Otto Karl Robert Wernicke (30 September 1893, Osterode am Harz – 7 November 1965) was a German actor. He is best known for his role as police inspector Karl Lohmann in the two Fritz Lang films M and The Testament of Dr. Mabuse. Married to a Jewish woman, he was only able to continue working in Germany after the Nazi Party took power in 1933 because he received a special dispensation from the Reich Chamber of Culture.
