Marianne Simson began her career as a ballerina in Berlin Opera ballet. Her film career took off during the WW II. She was a sporty, beautiful blonde who was cast in both musicals, historical adventures and dramas.

By that time she was rumored to be Dr Joseph Goebbel's lover. At the end of the war, she was arrested by the Russians, convicted and sent to a prison camp, where she nevertheless was active in organizing performances and giving song recitals. After the war she was seen on the screen in a film called Eine Alltägliche Geschichte (An Everyday Story), which was shot during the war, but was in musical synchronization when the war ended. She was released from the prison camp only in 1952, and never resumed her acting career, instead becoming a choreographer.

She was obviously quite renowned also as a ballerina, since in 1941 a porcelain figurine was produced, depicting her on her toes. The figurine was reproduced in around 1957 by the company Rosenthal, and bears her name underneath.
