At which Oxford college did C.S. Lewis teach and serve as a fellow for nearly three decades?

C.S. Lewis taught and served as a fellow at Magdalen College, Oxford, for nearly three decades. He was elected to a fellowship there in 1925 and remained at the college until 1954.

At Magdalen, Lewis taught English literature and built the academic career that made him an important medievalist and Renaissance scholar. He was especially associated with the study of older literature, including works by John Milton and the literature of the Middle Ages. His Oxford years also placed him in contact with fellow writers and scholars.

Lewis was a member of the Inklings, an informal Oxford literary discussion group whose participants included J.R.R. Tolkien and Charles Williams. Meetings and conversations among these writers helped create an important literary network, although the Inklings was not an official college society.

In 1954 Lewis left Oxford for Cambridge University, where he became the first holder of the newly established Chair of Medieval and Renaissance English. Magdalen therefore belongs to his Oxford career, while Cambridge belongs to his later professorship.
