The astonishing story of Dr. Josephine Janina Mehlberg--a Jewish mathematician who saved thousands of lives in Nazi-occupied Poland by masquerading as a Polish aristocrat--drawing on Mehlberg's own unpublished memoir. World War II and the Holocaust have given rise to many stories of resistance and rescue, but The Counterfeit Countess is unique. It tells the remarkable, unknown story of "Countess Janina Suchodolska," a Jewish woman who rescued more than 10,000 Poles imprisoned by Poland's Nazi occupiers. Mehlberg operated in Lublin, Poland, headquarters of Aktion Reinhard, the SS operation that murdered 1.7 million Jews in occupied Poland. Using the identity papers of a Polish aristocrat, she worked as a welfare official while also serving in the Polish resistance. With guile, cajolery, and steely persistence, the "Countess" persuaded SS officials to release thousands of Poles from the Majdanek concentration camp. She won permission to deliver food and medicine--even decorated Christmas trees--for thousands more of the camp's prisoners. At the same time, she personally smuggled supplies and messages to resistance fighters imprisoned at Majdanek, where 63,000 Jews were murdered in gas chambers and shooting pits. Incredibly, she eluded detection, and ultimately survived the war and emigrated to the US. Drawing on the manuscript of Mehlberg's own unpublished memoir, supplemented with prodigious research, Elizabeth White and Joanna Sliwa, professional historians and Holocaust experts, have uncovered the full story of this remarkable woman. They interweave Mehlberg's sometimes harrowing personal testimony with broader historical narrative. Like The Light of Days, Schindler's List, and Irena's Children, The Counterfeit Countess is an unforgettable account of inspiring courage in the face of unspeakable cruelty.

Winner of the 2020 Ernst Fraenkel Prize from the Wiener Holocaust Library​ Jewish Childhood in Kraków is the first book to tell the history of Kraków in the second World War through the lens of Jewish children’s experiences. Here, children assume center stage as historical actors whose recollections and experiences deserve to be told, analyzed, and treated seriously. Sliwa scours archives to tell their story, gleaning evidence from the records of the German authorities, Polish neighbors, Jewish community and family, and the children themselves to explore the Holocaust in German-occupied Poland and in Kraków in particular. A microhistory of a place, a people, and daily life, this book plumbs the decisions and behaviors of ordinary people in extraordinary times. Offering a window onto human relations and ethnic tensions in times of rampant violence, Jewish Childhood in Kraków is an effort both to understand the past and to reflect on the position of young people during humanitarian crises.
