Katalin Weinberger was also in a German concentration camp at the end of World War II. There she helped save the life of her sister, Charlotte Frimm, when she was sick with typhus.
Katalin buried her sister in a remote part of the camp with just a small pipe sticking up through the soil for her to breathe. For 30 days she snuck food and water to her sister. A Jewish doctor at the camp snuck medicine to her."
