Who completed and edited many of J.R.R. Tolkien’s posthumous Middle-earth publications?

Christopher Tolkien completed and edited many of J.R.R. Tolkien’s posthumous Middle-earth publications.

Christopher Tolkien was Tolkien’s third son and became the literary executor of his father’s estate. After J.R.R. Tolkien died in 1973, Christopher worked through extensive drafts, notes, maps, and variant texts.

His editorial work produced The Silmarillion, published in 1977, as well as Unfinished Tales and the twelve-volume History of Middle-earth. These books made otherwise unpublished or incomplete material available to readers while showing how Tolkien’s ideas changed over time.

Christopher did not simply reproduce finished manuscripts. He had to arrange fragments and make editorial decisions, especially for The Silmarillion. His work is therefore central to how later readers encounter Tolkien’s wider mythology.
