In a moment of distraction from the laborious work of marking an “enormous pile of examination papers”, J.R.R. Tolkien flipped to a blank page on a student essay and scribbled, “in a hole in the ground there lived a hobbit”.
This became the first line of The Hobbit (1937). From this doodle Tolkien went on to write one of the world’s most popular fantasy adventure series, The Lord of the Rings (1954).
