[close] Christopher Reuel Tolkien is the youngest son of the author J. R. R. Tolkien (1892–1973), and is best known as the editor of much of his father's posthumously published work. He drew the original maps for his father's The Lord of the Rings, which he signed C. J. R. T. The J. stands for John, a baptismal name that he does not ordinarily use.

J. R. R. Tolkien wrote a great deal of material connected to the Middle-earth mythos that was not published in his lifetime. Although he had originally intended to publish The Silmarillion along with The Lord of the Rings, and parts of it were in a finished state, he died in 1973 with the project unfinished.

After his father's death, Christopher Tolkien embarked on organizing the masses of his father's notes, some of them written on odd scraps of paper a half-century earlier. Much of the material was handwritten; frequently a fair draft was written over a half-erased first draft, and names of characters routinely changed between the beginning and end of the same draft. Deciphering this was an arduous task, and perhaps only someone with personal experience of J. R. R. Tolkien and the evolution of his stories could have made any sense of it. Christopher Tolkien has admitted to having to occasionally guess at what his father intended. [close]
