Heroes
Inspirational, to say the least. Consider this the short of a long list, but these are at the top. Though they come from a raft of different media, they are all most definitely storytellers first and foremost. And that's what I most like about them.

   Ray Bradbury
   Johnny Cash
   Hergé
   Alfred Hitchcock
   Elmore Leonard
   Charles Schultz
   Rod Serling
   George Bernard Shaw
   Jim Thompson

I deliberately left off any game designers, since it is less of a storytelling medium. If you want to see who they are, see my book on game design. I was lucky enough to interview my top seven.
