Stanislawa Leszczynska, a Polish midwife imprisoned at the Auschwitz-Birkenau death camp in Nazi-occupied Poland, delivered 3,000 babies of different nationalities and treated them and their mothers with heroic humanity. “Everyone has heard of Josef Mengele, but few know of Stanislawa Leszczynska. Even in Poland she’s not as well-known as she should be,” says Maria Stachurska, Leszczynska’s grand-niece. The cause for her sainthood is underway.
