Neil Gaiman it is probably one of his most famous works with the only other two that come close to it in fame is Sandman, and Stardust.

That said he has written so much stuff, from novels, to tv and movies, to comic books (where he got his start, but he did not focus on superhero comics but instead more comic stories), it is insane to list all of the stuff he has done
