Alonso III de Fonseca
Alonso III de Fonseca (c. 1475–1534) was a Galician churchman and statesman, son of Archbishop Alonso II. He became Archbishop of Santiago de Compostela in 1507, and Charles V later appointed him to the royal council.
A Renaissance humanist in touch with Erasmus, he made the University of Santiago de Compostela a major center of learning and founded the college named for him. In 1523 he was promoted to Archbishop of Toledo, primate of Spain, and in 1527 he baptized the future Philip II. He died at Alcalá de Henares in 1534.
