1380–1444 (age 64)·Italian Franciscan missionary and saint·Birthday: September 8
Biography
Born into a noble Sienese family orphaned by the plague, Bernardino Albizzeschi turned his back on wealth for the austere life of a Franciscan friar. His true calling emerged not in quiet contemplation, but in the public squares of Italy's fractious city-states. With a voice described as powerful enough to carry across thousands, he delivered electrifying sermons that tackled everything from usury and gambling to the bitter factionalism of the Guelphs and Ghibellines. His most famous visual prop was a wooden tablet inscribed with the initials 'IHS', the Holy Name of Jesus, which he held aloft to focus the crowd's devotion away from partisan symbols. Beyond the pulpit, he was a keen observer of commerce, writing treatises that justified fair trade and market prices, earning him a posthumous reputation as a foundational thinker in economic ethics. His relentless travel and populist approach revitalized lay piety and helped pave the way for the observant reform movement within his order.
