About this person
Roger Bacon, born around 1219 in England, became a Franciscan friar who thought Catholic faith and hands-on observation belonged together. He read the work of Ibn al-Haytham and noticed that running experiments sometimes proved Aristotle wrong, a method he learned partly from his teacher Robert Grosseteste. In 1267 he sent his Opus Majus to Pope Clement IV, a sprawling argument for empirical study that helped get optics added to university courses. He also wrote down Europe's first recorded formula for gunpowder, borrowed from Chinese sources. He worked on universal grammar and died around 1292, but by the early modern period the legend had shifted: people started calling him Doctor Mirabilis and spinning tales of necromancy and mechanical heads.
