John Ronald Reuel Tolkien, CBE (3 January 1892 – 2 September 1973), whose surname is pronounced /ˈtɒlkiːn/ (in General American also /ˈtoʊlkiːn/), was an English writer, poet, philologist, and university professor, best known as the author of the classic high fantasy works The Hobbit, The Lord of the Rings, and The Silmarillion. Tolkien was Rawlinson and Bosworth Professor of Anglo-Saxon at Oxford University from 1925 to 1945 and Merton Professor of English Language and Literature there from 1945 to 1959. He was a close friend of C. S. Lewis—they were both members of the informal literary discussion group known as the Inklings. Tolkien was appointed a Commander of the Order of the British Empire by Queen Elizabeth II on 28 March 1972. After his death, Tolkien's son, Christopher, published a series of works based on his father's extensive notes and unpublished manuscripts, including The Silmarillion. These, together with The Hobbit and The Lord of the Rings, form a connected body of tales, poems, fictional histories, invented languages, and literary essays about an imagined world called Arda, and Middle-earth within it. Between 1951 and 1955 Tolkien applied the word legendarium to the larger part of these writings. While many other authors had published works of fantasy before Tolkien, the great success of The Hobbit and The Lord of the Rings when they were published in paperback in the United States led directly to a popular resurgence of the genre. This has caused Tolkien to be popularly identified as the "father" of modern fantasy literature—or, more precisely, of high fantasy. Tolkien's writings have inspired many other works of fantasy and have had a lasting effect on the entire field. In 2008, The Times ranked him sixth on a list of "The 50 greatest British writers since 1945".
