Berkeley Breathed has sent Opus off to a warm and loving nap spot. Clement Hurd, the illustrator of Goodnight Moon, owed his career in children’s books to Margaret Wise Brown, the author of that same bedtime classic. Brown wrote a book, Bumble Bugs and Elephants, in 1938 specifically to showcase Hurd’s talents. Their subsequent collaborations on The Runaway Bunny and Goodnight Moon anchored their place of honor in childrens’ libraries. Years after his death in 1988, Clement Hurd made news again in 2005 when HarperCollins decided to remove the cigarette from his photo on Goodnight Moon. His estate agreed to the alteration (Hurd quit smoking in the 1950s) but some purists were not amused.
