To be fair, Aragorn does use an off-hand weapon (torch or dagger) to complement his bastard sword a few times, especially in the movies. But yeah, Drizzt is probably the main reason Rangers got TWF "subsidies."
Incidentally, I think the non-D&D literary character that best matches the D&D Ranger archetype might be Prince Gwydion from the Prydain Chronicles. He even casts Entangle (explicitly using magic to do so) in the first book. And has an obviously extraordinary bond with his horse. I don't think he uses TWF or archery much though.
But I don't like the magicky bits of the Ranger in D&D.
