St. Edith Stein (AD 1891-1942) was a German philosopher who studied and collaborated with Edmund Husserl, the founder of the phenomenological movement. Born of a Jewish family, she converted to Catholicism and later became a Carmelite nun, taking the name Teresa Benedicta of the Cross. The Nazis arrested her, and she died in Auschwitz on August 9, 1942. In her masterpiece, Finite and Eternal Being, she uses her phenomenological skills to enrich the metaphysics of St. Thomas Aquinas.
