No one, well that's not realy true, I guess some people inspire me. but I don't realy know (I guess it's in my nature, maybe I'm just arrogant).
But however, I still get inspired by books, movies etc. so in a way, their authors/ writers inspire me.
(For example, I was just reading 1984 again, and that inspired me in a way, or caused me to think to say the least, I wouldn't call George Orwells my hero though, I'm that much of a nerd).
