At which Oxford college was C.S. Lewis a Fellow and tutor in English?

C.S. Lewis was a Fellow and tutor in English at Magdalen College, Oxford. He held that position from 1925 until 1954, teaching students while developing the literary and theological work that made him famous.

Magdalen College is one of the constituent colleges of the University of Oxford and is located beside the River Cherwell. Lewis's rooms and the college grounds became closely associated with his Oxford years. He also participated in Oxford's intellectual and literary life through friendships and discussion groups.

Lewis left Oxford for Cambridge in 1954, becoming the first holder of the chair of Medieval and Renaissance Literature at Magdalene College, Cambridge. The similar names of Magdalen College, Oxford, and Magdalene College, Cambridge, can easily cause confusion, but his long Oxford fellowship was at Magdalen.
