At which university did J.R.R. Tolkien teach before moving to Oxford?

Before moving to Oxford, J.R.R. Tolkien taught at the University of Leeds.

Tolkien joined the University of Leeds in 1920 as a reader in English language. He became a professor there in 1924 and remained at Leeds until 1925, when he moved to Oxford to take the Rawlinson and Bosworth Professorship of Anglo-Saxon at Pembroke College.

His Leeds years were important professionally and personally. At Leeds, Tolkien worked with E. V. Gordon on the influential 1925 edition of Sir Gawain and the Green Knight. He also helped develop the English School and continued the linguistic and medieval studies that shaped his later fiction.

The University of Leeds is distinct from Oxford University, where Tolkien spent most of his academic career. He later held posts at Pembroke College and Merton College, Oxford, and retired from his Merton professorship in 1959.
