Fanny Petzal née Oppenheimer was born on 16 March 1915 in Frankfurt am Main. She was the daughter of Joseph (Yosef) Seligman Oppenheimer and Josephina Veronica Oppenheimer and had two brothers. The Oppenheimers were a large and wealthy family who founded the largest private bank in Europe. We do not know how closely her part of the family was connected with the banking business.
She married Werner in Holland in 1939. All we know about Fanny is that she was a physiotherapist.
The family lived in Hilversum in Pieter den Hoog Straat. Their son Bernhard Wolfgang was born there in 1941. In 1942, they were all deported to the Westerbork camp, where the twins Elisabeth Jeanne and Robert Harry were born a year later.
Fanny, Werner, their three children and Selma Petzal were taken from the Westerbork camp to Theresienstadt on the same transport in 1944. On 16 October 1944, they were deported from there to Auschwitz. Fanny, Selma and the children were murdered two days later, on 18 October 1944.
