Jean-Baptiste Muard was a nineteenth-century French Benedictine priest and theologian born in Vireaux. After completing his studies at the Auxerre Petit Séminaire, he was ordained on May 4, 1834. He served as a parish priest in Joux-la-Ville and conducted a successful mission in Pontaubert, during which he sought counsel from John Vianney. Muard is primarily recognized for his significant contributions to monastic life, including the establishment of the French province of the Cassinese Congregation and the founding of the Abbey of la Pierre-qui-Vire.
