C.S. Lewis spent most of his academic career in Oxford before moving to Cambridge.
Lewis taught English at Magdalen College, Oxford, beginning in 1925, and remained associated with the university for nearly three decades. Oxford became the setting for much of his professional life, his friendships with writers, and meetings of the literary group known as the Inklings.
The Inklings included Lewis, J.R.R. Tolkien, Charles Williams, and other writers and scholars. They discussed unfinished manuscripts, mythology, theology, and literature, often meeting at Oxford’s Eagle and Child pub or in college rooms. Lewis also wrote many major works in Oxford, including The Allegory of Love and The Problem of Pain.
Cambridge was also important: Lewis became a professor there in 1954. However, Cambridge was the later stage of his academic career. Belfast was his birthplace, and London was associated with some broadcasting and publishing activity, but neither city was his principal university home.
