 Edith Stein (1891–1942) was a realist phenomenologist associated with the Göttingen school and later a Christian metaphysician. She was a Jew who converted to Catholicism in 1922 and was ordained a Carmelite nun in 1933. She died in Auschwitz in 1942. She was subsequently declared a Catholic martyr and saint. She campaigned publicly on issues relating to women’s rights and education. Stein is known philosophically primarily for her phenomenological work on empathy and affectivity, her contributions as research assistant to Edmund Husserl, and her philosophical anthropology. She was in discussion with leading philosophers of her day, including Husserl, Scheler, Heidegger, Conrad-Martius, Ingarden, and Maritain. Her work contains original approaches to empathy, embodiment, the emotions, personhood, collective intentionality, and the nature of the state. In her later work, Stein developed an original philosophy of being and essence that integrated Husserlian phenomenology and Thomist metaphysics.
