Regina Świda lived with her husband Stanisław and their children Dominik and Renata in a rented apartment in the center of Warsaw. In the summer of 1943 her sister, who was active in the resistance, brought the Jewish boy Abraham Horowitz to the Świdas. His family had escaped from the ghetto and now had to hide. To explain the three-year-old’s circumcision, the Świdas claimed he was the orphaned son of a Tatar friend, and obtained papers for him under this new identity. This meant Abraham Horowitz could live with the Świda family rather than in hiding.
Regina Świda’s husband was killed during the Warsaw Uprising. After the uprising was quashed in October 1944, she was interned with Abraham Horowitz in transit camp 121 at Pruszków. On their release they moved to a village near Warsaw. Shortly before liberation in May 1945, Abraham’s mother collected her son from Regina Świda. Tatiana Horowitz had survived in hiding in Warsaw.
In 2011 Regina Świda was honored posthumously as Righteous Among the Nations by the Israeli Holocaust memorial center Yad Vashem.
