Who completed the editorial work for J.R.R. Tolkien’s posthumous book The Silmarillion?

Christopher Tolkien completed the editorial work for J.R.R. Tolkien’s posthumous book The Silmarillion.

Christopher Tolkien was J.R.R. Tolkien’s third son and became the principal editor of his father’s unpublished writings. After Tolkien died in 1973, Christopher selected, organized, compared, and sometimes connected many versions of the stories that formed The Silmarillion. The book appeared in 1977.

The editorial task was difficult because Tolkien had revised his mythology repeatedly across decades. The manuscripts included different names, events, tones, and levels of completion. Christopher’s published arrangement therefore presents a coherent reading of material that was not left by Tolkien as a final, press-ready manuscript.

Christopher continued editing his father’s papers in later books, including Unfinished Tales and the twelve-volume History of Middle-earth. This work made a large portion of Tolkien’s drafts available to readers, while also requiring editorial decisions that scholars and fans continue to discuss. He was not the author of the original mythology, but he was central to its publication history.
