At which Oxford college did J.R.R. Tolkien begin his professorship in 1925?

J.R.R. Tolkien began his Oxford professorship at Pembroke College in 1925. He became Rawlinson and Bosworth Professor of Anglo-Saxon, a position he held until 1945.

At Pembroke, Tolkien taught and researched Old English language and literature. His academic expertise included texts such as Beowulf, and his scholarship on medieval languages and stories influenced the texture of his invented mythology. He also wrote much of The Hobbit during his Pembroke years.

In 1945, Tolkien moved to Merton College, Oxford, where he became Merton Professor of English Language and Literature. He remained there until his retirement in 1959. Because both colleges are central to his Oxford career, biographies sometimes mention Merton first when discussing his later academic life, but Pembroke was the college where his Oxford professorship began.
