Roger Bacon (c. 1214–1294), also known as Doctor Mirabilis, was one of the most famous Franciscan friars of his time. An English philosopher who placed considerable emphasis on empiricism, he was one of the earliest European advocates of the modern scientific method. Later studies have emphasised his reliance on occult and alchemical traditions. Wikipedia
