Mitchison was educated in Oxford, and contributed verse to Oxford Poetry for 1915 and 1916 (in the former, in company with J.R.R. Tolkien's "Goblin Feet"). Eventually, she became a prolific writer of books and articles, including Graeme and the Dragon (1954, illustrated by Pauline Baynes) and To the Chapel Perilous (1955, which Tolkien disliked).
For many years, Mitchison was a fan of Tolkien's works, and they had a long-time correspondance. She became a proofreader of The Lord of the Rings when George Allen & Unwin sent her advance proofs of the first two volumes. Of The Fellowship of the Ring, Mitchison wrote "It is timeless and will go on".
However, later in life she became increasingly critical of Tolkien's works, critizing the "grandiose style" of The Return of the King and the lack of a feminine perspective in The Lord of the Rings and finding The Silmarillion simplistic.
