Edith Stein, also Saint Teresia Benedicta of the Cross, was a German Roman Catholic philosopher and Carmelite nun, a martyr and a saint of the Roman Catholic Church. Born into an observant Jewish family but an atheist by her teenage years, she was baptized on January 1, 1922 into the Roman Catholic Church. Stein and her sister Rosa, also a convert, were captured and shipped to the Auschwitz concentration camp, where they are presumed to have been gassed on August 9, 1942 when Edith was 50.
