Władysława Bartkowiak (Sister Euzebia) founded the Sisters of Resurrection Convent in Mir (Belarus) in 1936. In August 1942 Oswald Rufeisen, a Jewish man who had escaped from the Germans, asked the convent for help. Mother Superior Bartkowiak hid him in the loft of the convent’s grain store. Although the convent was close to the German police station, Bartkowiak decided to offer Rufeisen a permanent refuge. When danger loomed, Rufeisen disguised himself as a nun. Bartkowiak forged a close friendship with Rufeisen, who showed interest in her faith and was eventually baptized by her. When the Germans increased their searches for Jews in hiding, Rufeisen left the convent at the end of 1943 to protect the nuns. After liberation in the summer of 1944, Rufeisen visited his rescuer Euzebia Bartkowiak. She introduced him to Carmelite monks in Wilna (Vilnius, Lithuania), an order he later joined.
In 2002 Władysława Bartkowiak was posthumously honored by the Israeli Holocaust Memorial Center as Righteous Among the Nations.
