Stanisława Leszczyńska (May 8, 1896 – March 11, 1974) was a Polish midwife who was incarcerated at the Auschwitz concentration camp during World War II, where she delivered over 3,000 children.

[2] Stanisława Leszczyńska was born to a Polish Catholic family of carpenter Jan Zambrzycki and his wife Henryka, in the Bałuty neighborhood of Łódź in the Vistula Land under the Tsarist rule.

To make ends meet, her mother worked 12-hour shifts at the Poznański factory; her earnings allowed Stanisława to go to a private school where Polish was the medium of instruction.

[3] Upon her father's return to Poland, the family left for Brazil in 1908 seeking greater economic opportunity, and stayed in Rio de Janeiro.

[9] Stanisława met Dr Mengele,[4] and was advised to write reports about birth problems and diseases in the childbed.

[10] Years later, she described how she put her life at risk to save newborns in a work called Raport położnej z Oświęcimia (The Report of a Midwife from Auschwitz).

Expectant mothers did not realize what was going to happen to their babies and many traded their meager rations for fabric to be used for diapers after the birth.

On January 27, 1970 Stanisława attended an official celebration in Warsaw, where she met the women prisoners of Auschwitz and their grown-up children who had been born in the camp.
