St. Albertus Magnus, also known as Albert the Great and "the teacher of everything there is to know" can be characterized as a "renaissance man" even before there was such a word. He was a grand thinker, prolific writer and distinguished philosopher during the period of the Middle Ages. One of his pupils was another brilliant mind, St. Thomas Aquinas. The topics that were influenced by him are incredibly diverse and include psychology, logic, metaphysics, meteorology, mineralogy and zoology.
O God, who gavest grace unto blessed Albert, thy bishop and doctor, to become great because of his subjection of this world’s wisdom to a childlike faith in thee: Grant us, we beseech thee; in such wise to follow his doctrine that finally we may enjoy the fullness of thy light in heaven; through Jesus Christ thy Son our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, ever one God, world without end. Amen.
