Under the noses of the Gestapo, Agnieszka Budna-Widerschal, a catholic peasant woman from northern Poland, ventured into the Warsaw ghetto to save her Jewish husband and his five cousins. She hid them for three years in Poland, the most dangerous of countries for Jews fleeing the Holocaust. Germans considered Poles to be racially inferior, killing 1.5 million non-Jewish Polish citizens during World War II.
In 1954, her 9-year-old daughter was pushed onto a train track by Polish anti-Semites. Agnieszka and her husband moved to Israel after the girl’s tragic death.
