In 1921, she read the autobiography of St. Teresa of Avila, and was moved to convert. In 1934, Edith entered a Carmelite convent, and took the name Teresa Benedicta of the Cross. She prayed especially for Jews in Germany, who were being persecuted under Hitler during World War II. Teresa Benedicta was arrested, along with her sister Rosa, who had also converted, and the other sisters in her religious community. St. Teresa Benedicta died in the concentration camp at Auschwitz on August 9, 1942.
