At which university did C.S. Lewis teach from 1925 until 1954?

C.S. Lewis taught at the University of Oxford from 1925 until 1954.

Lewis became a fellow and tutor in English at Magdalen College, Oxford, in 1925. He remained there for nearly three decades and developed a reputation as a literary scholar, lecturer, essayist, and Christian writer. Oxford was also the setting for his friendships with fellow writers such as J.R.R. Tolkien and Charles Williams.

During his Oxford years, Lewis wrote major works including The Allegory of Love, The Problem of Pain, The Screwtape Letters, and the early Narnia novels. He also participated in the Inklings, an informal literary discussion group that met primarily at Oxford’s Eagle and Child pub.

In 1954, Lewis left Oxford for Cambridge University, where he became the first holder of the newly established Chair of Medieval and Renaissance English. He continued teaching at Cambridge until his death in 1963, but Oxford remains the institution most closely associated with his academic career.
