From the original "pulp" era: Sax Rohmer. Love that 1920s pulp fiction. He's horribly racist, but it's enjoyable if you just swap the "heroes" and "villians" in your head as you read. (Fu Manchu is the most evil man in the world because... he wants to free China from British colonial rule? Right. Go Fu Manchu!)
Also, Doc Savage. I like Doc in the same way I like the 60s Batman TV show: I don't particularly like the "heroes", I just enjoy the environment.

WHAT ELSE WILL THE FUTURE BRING!?!?)
