Absolutely J.R.R. Tolkien! He was brilliant, used words beautifully, and created the most epic tale in my knowledge. His books are a mixture of brilliance and magnificence. Among a list of very few, he is definitely a 'hero', to me.
In a way, Christopher Paolini.. Yeah, he took some stuff from LOTR, Star Wars, etc. etc. (but when you think about it, a lot of writers do this. The extent of which he did it, however, was too vast for me)
But, I mean, the support he got/gets from his family-- whoa! I wish I had that sort of support! (Writing feels so solitary! Especially when there's no one to read it. There are moments when I write something really well and long for someone to share it with.)
And now he'll probably be able to write as long as he wishes. Lucky boy!
Other writers like Jane Austen, Shannon Hale (love her vivid writing style), Mark Twain.. I could go on and on!
