Teresa Benedicta

Edith Stein (German: [ʃtaɪn]; in religion Teresa Benedicta of the Cross; 12 October 1891 – 9 August 1942) was a German philosopher who converted to Catholicism and became a Discalced Carmelite nun. She was murdered in the gas chamber at the Auschwitz II-Birkenau concentration camp on 9 August 1942, and is canonized as a martyr and saint of the Catholic Church; she is also one of six patron saints of Europe.
Stein was born into an observant German Jewish family, but had become an agnostic by her teenage years. Moved by the tragedies of World War I, in 1915, she took lessons to become a nursing assistant and worked in an infectious diseases hospital. After completing her doctoral thesis at the University of Freiburg in 1916, she obtained an assistantship to Edmund Husserl there.
From reading the life of the reformer of the Carmelites, Teresa of Ávila, Stein was drawn to the Christian faith. She was baptized on 1 January 1922 into the Catholic Church. At that point, she wanted to become a Discalced Carmelite nun but was dissuaded by her spiritual mentor, the archabbot of Beuron, Raphael Walzer OSB. She then taught at a Jewish school of education in Speyer. As a result of the requirement of an "Aryan certificate" for civil servants promulgated by the Nazi government in April 1933 as part of its Law for the Restoration of the Professional Civil Service, she had to quit her teaching position.
