Professor Mamlock, a respected Jewish surgeon, is certain that the Weimar Republic would survive the political crisis of the early 1930s. He disapproves of his son, Rolf, a communist activist who openly opposes the Nazis. When Hitler rises to power, Mamlock loses his work and his dignity. Realizing the mistake he made by being politically apathetic, Mamlock commits suicide. The film ends with his dead face blending away from the screen, on which appears the inscription: "there is no greater crime than not wanting to fight when fight one must."
The film was adapted from the playProfessor Mamlock, written by the director's father Friedrich Wolf during 1933, when he was in exile in France. It featured most of the cast that participated in the 1959 Kammerspiele staging of the play. When Wolf was asked why he decided to make another film adaptation of the play - the first was done in 1938 - he answered: "our objective was not the persecution of Jews... But the destiny of a liberal intellectual, who is forsaken by his class. This individual no longer believes in the middle class, and yet he does not find his way to the working class. His only escape becomes suicide".
Reception
Professor Mamlock sold 940,000 tickets in East Germany, becoming a modest commercial success. The film won the Gold Prize in the 2nd Moscow International Film Festival on 23 July 1961. Wolf also received the Silver Lotus Award in the IIInternational Film Festival of India, held in New Delhi in November 1961. Daniela Berghahn considered the film as "paradigmatic" to DEFA's treatment of the persecution of Jews by the Nazis: by contrasting the apolitical, lethargic Mamlock to his son, Rolf, the passionate communist and resistance fighter, Wolf condemned the professor for failing to join the resistance and "utterly scandalously... Made him accountable for his own fate." Anthony S. Coulson analyzed the picture as a belated metamorphosis of the title character, who ceases denying reality only when all is lost: "Mamlock's transformation is presented as a renunciation of his previous self... But that insight comes too late to save him and his kind... His fate is attributed to his failure to fight... Wolf's film reaffirms the political pathos of his father's play."
