Faye Schulman, a Holocaust survivor who lost most of her family to the Nazis but joined a group of partisan fighters and documented their work in photographs, died April 24. She was 101.

Schulman’s photographs often depicted the smiling faces of young partisan fighters, with Schulman at times at the center in a stylish leopard print coat. Michael Berkowitz, a professor of Jewish history at University College London, told The Forward that her photos were “extremely important in documenting the history of the resistance.”

Schulman’s family was killed in 1942 when the Nazis liquidated the ghetto in Lenin, Poland. She was saved due to her occupation; she was put to work photographing Nazi officials and developing prints.

She joined the partisans after escaping to the forests, and she became a nurse to wounded partisan soldiers. She was liberated by Soviet troops in 1944, and later that year married a fellow Jewish member of the partisans, Morris Schulman. In 1995, Schulman published a book, A Partisan’s Memoir: Woman of the Holocaust that included many of her photographs.
