J.R.R. Tolkien is well-known for changing the game for fantasy as a literary genre with his magnum opus, The Lord of the Rings. He pulled from many pre-established tropes in mythologies from around the world, but one creation he could claim as his own: hobbits. He started with The Hobbit in 1937, but even then, Tolkien had no idea what a tour de force his later works would become. He dedicated the prologue of The Fellowship of the Ring to an explanatory diatribe on Hobbits and their ways of life. And he'd later published a second, revised edition in 1951 in an effort to tie it into its epic sequel more.
