Albertus Magnus, (1193-1280), also known as Albert the Great and Albert of Cologne, is a Catholic saint. He was a German Dominican friar and a bishop who achieved fame for his comprehensive knowledge of and advocacy for the peaceful coexistence of science and religion. Those such as James A. Weisheipl and Joachim R. Soder have referred to him as the greatest German philosopher and theologian of the Middle Ages, an opinion supported by contemporaries such as Roger Bacon. The Catholic Church honours him as a Doctor of the Church, one of only 35 persons with that honor.
