Edith Stein

Edith Stein was a gifted philosopher, a student of Husserl, and by her teens had quietly given up God. Reading the autobiography of Teresa of Ávila straight through one night changed everything; she was baptized in 1922, became a Carmelite nun, and was murdered at Auschwitz in 1942. The Catholic Church later declared her a saint.
