What was the name of the Oxford college where J.R.R. Tolkien was a fellow from 1925 to 1945?

J.R.R. Tolkien was a fellow of Pembroke College, Oxford, from 1925 to 1945.

Tolkien joined Pembroke when he became Rawlinson and Bosworth Professor of Anglo-Saxon. During those two decades, he taught students, pursued philological research, and wrote major parts of The Hobbit and The Lord of the Rings. The college’s medieval buildings and academic setting formed part of his daily environment while Middle-earth was taking shape.

In 1945, Tolkien moved from Pembroke to Merton College after accepting the Merton Professorship of English Language and Literature. He remained at Merton until his retirement in 1959 and served as its Professor of English Language and Literature.

Pembroke is therefore associated especially with Tolkien’s Oxford years during the composition of his best-known fiction. Merton is also correctly linked to him, but it was his later college, not the one where he began his Oxford professorship.
