In 1916 she married Bronislaw Leszczynski, with whom she had two sons and a daughter. However, she was separated from the males in her family when Germany invaded Poland in 1939.
After being captured by the Nazis, she was sent with her daughter to the Auschwitz concentration camp, where as part of the Nazi practices, women who became pregnant were murdered, because they considered that babies were “useless” and delayed the births. work of mothers in the concentration camp.
For this reason, “Mutti” (Mother), as Stanislawa was nicknamed in the camp, had to improvise a “maternity ward” in the barracks that were next to the boilers, which were infested with all kinds of insects and humidity. However, that place became the salvation of thousands of mothers and unborn children. The midwife’s deep Catholic faith led her to baptize each newborn with the sign of the cross on her forehead.
“Mutti” was in Auschwitz until its liberation by Soviet troops on January 26, 1945, he died in 1974 and his cause for canonization has been introduced in the Diocese of Lodz.
