Tolkien is usually cited as the father of fantasy, but when you read his books the magic used in both the Hobbit and the Lord of the Rings, isn't really what most of us today think of when we say magic and fantasy.
We mostly think of it along the lines of D&D; casting fireballs, summoning creatures from another plane, etc.
Even Harry Potter, if you read it closely, has more in common with the D&D style of magic than what we see in Tolkien's work.
I don't know if Gary Gygax and Dave Arneson could be the answer for while Dungeons and Dragons is popular, I don't know if it was popular enough to effect culture, to start using magic in the way we often see it used and displayed in modern day literature and pop-culture
So my question is who would you say is the father/fathers of our modern day perception and use of magic in modern day literature and pop-culture?
Was it Gary Gygax and Dave Arneson or was it some other work of fiction mainly responsible for the whole casting fireballs, summoning lightning or demons and other stuff?
