St. Albert the Great (1206-1280) is known as one of the greatest thinkers of his day. Although he worked to develop many areas of study with his extensive knowledge in Science, Philosophy, and Theology, he was particularly involved with the natural sciences. He was the bishop of Regensburg, Germany, and was also taught the reknowned St. Thomas Acquinas. St. Albert died in 1280 and was declared a Doctor of the Church in 1931 by Pope Pius XI. St. Albert the Great is the patron saint of scientists, and his feast day is November 15th.
