Charles-Joseph-Eugene de Mazenod was a French aristocrat, missionary, and Catholic bishop who served as the Bishop of Marseille. Born in 1782, his early life was shaped by his family's flight to Italy to escape the French Revolution. After returning to France and undergoing a profound spiritual conversion, he dedicated his life to serving marginalized groups, including the poor and prisoners. He is most notably recognized as the founder of the Missionary Oblates of Mary Immaculate, a religious congregation that expanded its missionary work globally.
