J. R. R. Tolkien
From Tardis Wiki, the free Doctor Who reference
J.R.R. Tolkien was an Oxford don and the author of 'The Lord of the Rings'. While working at a garden centre, Fitz Kreiner had a conversation with a woman who incorrectly named him as R. J. Tolkien. Fitz convinced her that the character of Frodo had been named after a woman whom Tolkien had a relationship with. (EDA: The Taint)
