I can't speak of Tolkien with any semblance of objectivity, because the Lord of the Rings was what I had at a very vulnerable and troubled time in my life. That said, as a lover of language, his creation of languages remains amazing to me - even though I still find it odd that he had the Rohirrim speak Anglo-Saxon rather than creating a language for them too. Apparently they were the "hook" that tied his academic work (which, as you probably know, he was a renowned scholar as well) to his own inner fantasy life. 
But nobody's mentioned Ursula LeGuin yet??? Probably the first writer to bring feminism into the mainstream of FSF? (Okay, I totally had not heard of The Wild Girls before I just now checked out her website, and it's on my to-read list now...)
