Adjutor was a 12th-century Benedictine monk from Vernon, France, who is recognized as a saint in the Catholic tradition. Originally a knight, he participated in the First Crusade before undergoing a religious transformation. Following his experiences during the holy war, he lived as a recluse and hermit. He is primarily remembered for his connection to water, leading to his patronage of various groups including swimmers, boaters, and those who have nearly drowned.
