William of Perth was a 12th-century Scottish monk and baker who is venerated as a martyr. Born in Perth, he eventually dedicated his life to religious service after a youthful period of wandering. Known for his charity, he frequently donated bread to the impoverished and adopted an abandoned child, whom he trained in his trade. While traveling on a pilgrimage toward the Holy Places, William was murdered in Rochester, England, by his adopted son, who intended to rob him.
