Brébeuf was born 25 March 1593 in Condé-sur-Vire, Normandy, France. . He joined the Society of Jesus in 1617 at the age of 24, spending the next two years under the direction of Lancelot Marin. Between 1619 and 1621, he was a teacher at the college of Rouen. Brébeuf was nearly expelled from the Society when he contracted tuberculosis in 1620—a severe and usually fatal illness that prevented his studying and teaching for the traditional periods. His record as a student was not particularly distinguished, but Brébeuf was already beginning to show an aptitude for languages. Later in New France, he would teach Native American languages to missionaries and French traders. Brébeuf was ordained as a priest at Pontoise in February 1622.
