"The greatest crime in Auschwitz was to be pregnant. ... Dr. Mengele told me that it was my duty to report every pregnant woman to him... He said that they would go to another camp for better nutrition, even for milk. So women began to run directly to him, telling him, 'I am pregnant.' I learned that they were all taken to the research block to be used as guinea pigs [in medical experiments], and then two lives would be thrown into the crematorium. I decided that never again would there be a pregnant woman in Auschwitz."
