More than 70 years after Berthold’s death at Auschwitz his nephew Bruce wrote:
My father emigrated from Nazi Germany to the United States in 1939, not long after Kristallnacht. He grew up in a Jewish orphanage in Frankfurt with his younger brother, Berthold. My father, Georg, was five when he was taken into the orphanage. His brother was three. After completing Gymnasium in 1933, my father went to the only Jewish Teacher’s Seminary still operating in Nazi Germany (the same one that Walter Kaufmann attended at around the same time). After spending a couple of years teaching in a Jewish Day School, my father came to the United States and enrolled as an undergraduate at Yeshiva University. His brother chose to remain behind in Germany, becoming a Youth Aliyah Hachsharah training-camp director in Nazi-occupied Holland. In 1943, the Gestapo closed the camp and deported Berthold to Auschwitz.
