Asimov got me interested in science fiction, I swiftly jumped on all science fiction books I could find in the local libraries (I was a member of three of them at one point), and as they labeled fantasy as the same genre (visual labels, science fiction was a sort of cloud for some reason), I read all I could find of that too.
Regrettably, back in the day, that didn't amount to so many books.
But still, plenty of Zelazny, Asimov, Weis&Hickman, Tolkien,...
