However, I would like to recall that we venerate St Ursula and her companions here; that in 745 the Holy Father named St Boniface Archbishop of Cologne; that St Albert the Great, one of the most learned scholars of the Middle Ages, worked here and that his relics are venerated in the Church of St Andrew; that Thomas Aquinas, the greatest theologian of the West, studied and taught here; that in the 19th century Adolph Kolping founded an important social institution; that Edith Stein, a converted Jew, lived here in Cologne at the Carmelite Convent before being forced to flee to the Convent of Echt in Holland to be deported subsequently to Auschwitz, where she died a martyr. Thanks to these and all the other figures, both known and unknown, Cologne possesses a rich legacy of saints.
