It was there, in February 1944, that she and her father were arrested. They were sent to Drancy, a transport camp, and then to Auschwitz. She later learned through the research of an archivist that the man who had denounced the family was someone who would come to the chateau to gather hazelnuts that had fallen into the garden, Ms. Perrignon wrote in an article in Le Monde.

Ms. Loridan-Ivens is survived by a sister, Jacqueline. A brother and another sister committed suicide, she told the French magazine L’Humanité in 2015.

As a prisoner, Ms. Loridan-Ivens recalled, she was stripped naked and examined by the infamous Nazi doctor Josef Mengele. She was later one of the inmates selected by the Germans for evacuation as the Soviet Red Army closed in. She was taken first to the camp at Bergen-Belsen in Germany and then to Theresienstadt, near Prague.

On her return to France after the war she married Francis Loridan, but she left him soon after. She spent the next several years in Paris immersed in the Left Bank intellectual milieu of the 1950s, coming to know the semiotician and philosopher Roland Barthes and the philosopher and sociologist Edgar Morin.

It was Mr. Morin who, with Jean Rouch, a cinematographer, introduced her to film. She acted in “The Chronicle of a Summer” (1961), an experimental film, directed by the two men, about everyday life in Paris. She remained involved in cinema for the rest of her life, as an actress and then a director, as she became increasingly politically active.

During the 1950s and early ′60s Ms. Loridan-Ivens struggled to dispel some of her inner grief and to cope with the difficulties of being a survivor. She typed manuscripts for Mr. Barthes and acted in several films. It was a period of talking, reading, drinking, smoking and trying to reconstruct her life, although she spoke little if at all about her experiences in the camps.
