Roland Topor's father, who was Jewish, faced significant dangers during World War II due to the anti-Semitic policies of the Nazi regime and their collaborators. Initially, Topor's father was arrested and sent to the internment camp at Pithiviers, which was a holding camp for Jewish detainees before further deportation to concentration camps such as Auschwitz.

To save his family, Roland's father escaped and went into hiding. The family moved to Savoy, a region in France, to avoid capture by the Gestapo. They took extreme measures to disguise their identity, including baptizing Roland to hide his Jewish heritage. These actions were part of their efforts to survive during the Holocaust Source.
