Oxford hosted the college where C.S. Lewis taught for most of his career.
Lewis became a fellow and tutor in English at Magdalen College, Oxford, in 1925. He remained there until 1954, teaching medieval and Renaissance literature while writing fiction, literary criticism, and Christian apologetics.
Oxford was central to Lewis's intellectual and social life. He participated in informal discussions with fellow writers and scholars, including J.R.R. Tolkien, Charles Williams, and Owen Barfield. These meetings became associated with the Inklings, an influential literary discussion group.
Lewis later moved to Cambridge, where he became the first holder of the newly established chair of Medieval and Renaissance English in 1954. That later appointment is why Oxford and Cambridge are sometimes confused in summaries of his academic career.
