MORAUD, Dieudonne Gabriel Charles Henry (mo-ro), Swiss missionary, born in Soleure, Switzerland, about 1503 ; died in Brazil in 1572. He was a Jesuit, was sent in 1536 to Bahia, where he learned the Indian dialects, and employed afterward in the missions of the Mamalucos or half-breeds. In 1550 he became assistant to Leonardo Nunes, the superior general, and founded missions in the province of Espiritu Santo. When Ville-gaignon attacked Rio Janeiro in 1558, he marched to the succor of the city with a body of loyal indians, and was afterward employed as negotiator between the Portuguese authorities and the French admiral. He was also instrumental in bringing about the treaty of Upabeba with the Tupinambis, allies of the French, who devastated the Portuguese settlements, and became in 1567 visitor of the missions in south Brazil. He died from exhaustion during a journey through the province of Espiritu Santo. He left in manuscript "De arte linguae Tupiorum, guaranorumque," which has since been published in the collection of the "Bibliotheca Scriptorum Societatis Jesu."
