Magdalen College employed C.S. Lewis for most of his Oxford teaching career.
Lewis became a fellow and tutor in English at Magdalen College, Oxford, in 1925. He remained there for nearly three decades, teaching students, conducting tutorials, and writing many of the works that made him internationally known.
His rooms and daily routines at Oxford became closely associated with his academic life. Lewis participated in literary discussion groups, including the Inklings, whose members met regularly in Oxford and discussed works in progress, mythology, and Christian ideas.
Lewis left Oxford in 1954 to become the first Professor of Medieval and Renaissance English at Magdalene College, Cambridge. The two colleges have similar names but are different institutions: Magdalen College is in Oxford, while Magdalene College is in Cambridge. That distinction is one of the most frequent facts confused in accounts of his career.
