Which Tolkien son edited The History of Middle-earth after J.R.R. Tolkien’s death?

Christopher Tolkien edited The History of Middle-earth after J.R.R. Tolkien’s death.

The twelve-volume series was published between 1983 and 1996. Christopher Tolkien selected, arranged, transcribed, and explained drafts, notes, and other materials that documented the development of his father’s mythology. The books show how stories, names, maps, genealogies, and cosmological ideas changed across Tolkien’s lifetime.

Christopher had a particularly close relationship with the material. He helped create maps for The Lord of the Rings and served as a wartime pilot, but his most influential literary role came after his father died in 1973. His editorial work made a large amount of previously unpublished writing available to readers.

The series is not a straightforward sequel or continuous narrative. It is a history of Tolkien’s creative process, with editorial commentary and variant texts. Christopher Tolkien also edited The Silmarillion and Unfinished Tales.
