Portrait of Renate Müller, 1930s. On the back the actress' name is written with pencil. Renate Müller (26 April 1906 – 7 October 1937) was a German singer and actress in both silent films and sound films, as well as on stage. One of the most successful actresses in German films from the early 1930s, she was courted by the Nazi Party to appear in films that promoted their ideals, but refused. Her sudden death at the age of 31 was initially attributed to epilepsy, but after the end of World War II, witnesses suggested that she had been murdered by Gestapo officers, although another theory contends that she committed suicide. The true circumstances of her death remain unknown. (source: wikipedia.org)
