A Jewish professor in Poland, Dr. Josephine Mehlberg evaded capture under the Nazi occupation by posing as a Polish aristocrat using false papers. As “Countess Janina Suchodolska,” Mehlberg worked as a welfare official in Lublin, Poland—home of the infamous Majdanek concentration camp—where she smuggled food and medicine to prisoners, served in the Polish resistance, and eventually rescued more than 10,000 imprisoned Poles. Drawing on her unpublished memoir and prodigious research, historians Elizabeth B White and Joanna Sliwa bring to stunning life the astonishing true story of a remarkable woman previously lost to history.
