Jacques Berthieu was a 19th-century French Jesuit priest who served as a missionary in Madagascar. Born in Polminhac, France, he initially worked as a diocesan priest before joining the Society of Jesus to pursue missionary work in distant lands. After several years of service in various locations, including the islands of Réunion and Sainte-Marie, he moved to Madagascar to lead remote mission stations. He was killed in 1896 during the Menalamba rebellion, a period of violent revolt against European influence in the region.
