Which college of the University of Cambridge employed C.S. Lewis as a professor from 1954?

Magdalene College employed C.S. Lewis as a professor at the University of Cambridge from 1954. He held the newly established chair of Medieval and Renaissance English at Cambridge.

Before moving to Cambridge, Lewis had spent most of his academic career at Oxford. He was a fellow and tutor at Magdalen College, Oxford, from 1925 until 1954. The two institutions have similar names, making them an especially common source of confusion.

Lewis continued living near Oxford after taking the Cambridge post and travelled to Cambridge for his teaching and academic duties. His Cambridge appointment recognized his expertise in medieval and Renaissance literature, even though his public reputation increasingly rested on apologetics and fiction.

Magdalene is spelled with an “a” in the middle at Cambridge. Oxford’s college is spelled Magdalen, without the final “e.” That spelling distinction identifies the institution named in this question.
