At which university did C.S. Lewis hold a long-term academic post before moving to Cambridge?

C.S. Lewis held his long-term academic post at the University of Oxford before moving to Cambridge.

Lewis taught at Oxford from 1925 until 1954, first as a fellow and tutor at Magdalen College. His Oxford work focused on English literature, and he became known for both rigorous scholarship and an unusually broad ability to communicate literary ideas to general readers.

In 1954, Lewis accepted the newly established chair of Medieval and Renaissance Literature at the University of Cambridge. He became a fellow of Magdalene College, Cambridge, and continued teaching there until his death. The college name can cause confusion: Lewis was associated with Magdalen College at Oxford and Magdalene College at Cambridge, which are different institutions.

Oxford was also the setting for many of Lewis’s friendships, including his relationship with Tolkien and the meetings of the Inklings. Cambridge was his later academic base, not the university where he spent most of his teaching career.
