Jadwiga and Konstanty Apołłow, with their two daughters - Krysia (14 years old) and Irenka (6 years old) - lived in Warsaw at 6 Skorupka Street. Konstanty was a lawyer.
In the summer of 1942, as the Warsaw ghetto was in the process of being liquidated, Irena Skowronek, Jadwiga's sister, asked the Appołłow's to hide an elderly Jew. That person was Anna Neuding, who had managed to get to the "Aryan side"and needed shelter. Konstanty and Jadwiga took her into their home and cared for her for two months, until such time as a safe hiding-place could be found..
About the help she received, Anna wrote this in a testimony to the Jewish Historical Institute,
"In August 1942, straight after leaving the ghetto, I found shelter in the home of lawyer, Konstanty Apołłow. Knowing that (...), I had no documents, he took me in, even though the consequences could be drastic for him and for his family (...), in a totally selfless manner, he took care me (...). Thanks to his immense humanity, I managed to survive the most difficult and dangerous period of my life". (Source: The Book of the Righteous, ed Michał Grynberg, Warsaw 1993).
