Edith Stein, also known as St. Teresa Benedicta of the Cross (October 12, 1891 – August 9, 1942), was a German Jewish philosopher who converted to the Roman Catholic Church and became a Discalced Carmelite nun. She is a martyr and saint of the Catholic Church.
She was admitted to the Discalced Carmelite monastery in Cologne the following October. She received the religious habit of the Order as a novice in April 1934, taking the religious name Teresa Benedicta of the Cross (“Teresa blessed by the Cross”). In 1938 she and her sister Rosa, by then also a convert and an extern Sister of the monastery, were sent to the Carmelite monastery in Echt, Netherlands for their safety. Despite the Nazi invasion of that state in 1940, they remained undisturbed until they were arrested by the Nazis on August 2, 1942 and sent to the Auschwitz concentration camp, where they died in the gas chamber on August 9, 1942.
