Marianne Hendrix is the daughter of Paul Hendrix and Berthe Hendrix-Vles. She was born January 28, 1939 in Amsterdam, where her father was a prosperous stockbroker, and her mother, who had studied law, was a housewife. Marianne had two older brothers: Robert Alexander (b.1930) and Hans Leonard (b. 1933). After the German invasion of the Netherlands, Paul served on the finance committee of the Amsterdam Jewish Council. He had hoped that this would protect the family from deportation. However, on September 23, 1943, the entire family was rounded-up and sent to Westerbork. While incarcerated in Westerbork, Paul was occasionally sent back to Amsterdam on behalf of the Council. He realized that Marianne was too young to survive the harsh conditions at the camp. In order to secure her release, he declared her to be an illegitimate child. In February 1944 she was sent to live with her mother's sister, Dora, and her non-Jewish husband. During the summer of 1944 the rest of the family was sent to Theresienstadt. From there, they were deported to Auschwitz. Marianne's mother and brother, Hans Leonard, perished on October 25, 1944; her father died in Golleschau, a subcamp of Auschwitz, on December 14, 1944; and her brother Robert died in Mauthausen shortly before the liberation on March 30, 1945. After the war, Marianne continued to live with her aunt and uncle.
