C.S. Lewis became a professor at Cambridge University in 1954. He was appointed the first holder of the newly created Chair of Medieval and Renaissance Literature at Magdalene College, Cambridge.
The appointment came after Lewis had spent most of his academic career at Oxford. He had been a fellow and tutor at Magdalen College, Oxford, where he taught English literature and developed a reputation as a medieval and Renaissance scholar.
Lewis continued living in Oxford after moving to Cambridge for his professorship. He regularly traveled between the two universities, and his Cambridge position gave him a formal academic base during the final years of his career.
The Cambridge appointment is sometimes mistaken for the start of Lewis’s teaching career. It was actually a later promotion and a change of university. His major Oxford appointment began decades earlier, while his Cambridge chair lasted from 1954 until his death in 1963.
