Hilary of Poitiers - Known as the first great Christian thinker from France, he was noted as a defender of the faith and a scholar who helped to change the course of religious history in the West. He wrote the first lengthy study of the doctrine in Latin, introduced Eastern theology to the West, and contributed to the development of hymnology. The son of pagan parents, he was received into the church at the age of 30 and later was named Bishop of Poitiers. He died in 366.
