Marist Brothers High School was founded and has been run by members of the Marist Brothers order since it opened to students in 1949. Founded by Saint Marcellin Champagnat, a Marist priest in France in 1816, the order went by the names of the "Petits Frères de Marie" (Little Brothers of Mary) and "Fratres Maristae a Scolis" (FMS or the Marist Brothers of the Schools, the post-nominal letters of the Marist Brothers). Marcellin's desire to have brothers to teach the rural children grew after his visit to the bedside of a sixteen-year-old, Jean Baptiste Montagne whom St. Marcellin discovered knew nothing of his faith.
