9. Edith Stein (Saint Teresa Benedicta of the Cross)
Edith Stein, born into a Jewish family, converted to Catholicism and became a prominent philosopher and Carmelite nun. Her arrest and execution at Auschwitz in 1942 marked her as a martyr of both faith and conscience. Stein’s life and writings emphasize interfaith dialogue, intellectual pursuit, and steadfast resistance to tyranny, making her a symbol of moral courage in the face of oppression (via United States Holocaust Memorial Museum).
