Bertje Leuw (* 1944) was born to Jewish parents who lived underground in the Netherlands and had to change hiding places nine times with the baby. Bertje’s sister, who was three years older, and her brother, who was one and a half years older, had already been placed in foster families in the spring of 1943; after the liberation of the Netherlands by the Allies, her siblings were reunited with their parents – the brother after months of searching. Leuw worked as a family therapist and as a lecturer in social work training. Out of an inner need to publicize literature about the Holocaust, she wrote book reviews for the newspaper editors of the Dutch Auschwitz Committee for over 30 years. In 2015, Bertje Leuw published a book based on a play that her deaf brother had performed in sign language about the family history: “Kleine Maurits, een oorlogsverhaal in gebaren” (Little Maurits, a war story in signs).
