As reported on Reddit, JRR Tolkien's youngest son Chrisopher Tolkien (21 November 1924 – 15 January 2020) has passed away.
He will be remembered as a great preserver of his father's legacy and an editor of his father's unfinished works. He also drew many of the wonderful maps of Middle-earth. I am thankful for what he did to bring those works to the public.
Rest in Peace.
