At which university did C.S. Lewis hold a fellowship and teach English for most of his career?

C.S. Lewis held a fellowship and taught English at the University of Oxford for most of his career.

Lewis became a Fellow and Tutor in English Literature at Magdalen College, Oxford, in 1925. He remained associated with the college until 1954, teaching students and developing a major reputation as a medieval and Renaissance literary scholar. His Oxford friendships included J.R.R. Tolkien and Charles Williams, and the informal literary group known as the Inklings met during this period.

In 1954, Lewis left Oxford for Cambridge University, where he became the first holder of the Mediaeval and Renaissance English chair. He was also a Fellow of Magdalene College, Cambridge. That later appointment is why answers sometimes incorrectly identify Cambridge as the university where he spent most of his teaching career.

Oxford shaped both Lewis’s academic work and his literary community. Cambridge was important during the final years of his professional life, but Oxford was the longer and more formative institutional home.
