At which university did C.S. Lewis hold a professorship of medieval and Renaissance literature?

C.S. Lewis held a professorship of medieval and Renaissance literature at the University of Cambridge. He took up the Cambridge position in 1954 and remained associated with Magdalene College until his death.

Before Cambridge, Lewis spent most of his academic career at the University of Oxford. He taught English at Oxford from 1925 and became a Fellow and Tutor of Magdalen College. His Oxford years included close friendships with writers such as J.R.R. Tolkien and Charles Williams, as well as participation in the literary discussion group known as the Inklings.

The university distinction is a common source of confusion. Lewis is strongly identified with Oxford because of the length of his career there and the setting of his professional and personal life. Cambridge, however, was the institution that appointed him to the senior chair in medieval and Renaissance literature. His move did not erase his Oxford connections, and he continued to be remembered as an Oxford intellectual.
