Well it's the closest I can come up with right now, I like some of Lovecraft's as he was able to capture a sense of 'civilization under threat' and actually fuelled horror-writing (S. King often states he was an inspiration).
Heinlen has that ballsy, gutsy vibe while not falling into any pigeonhole (people call him ultra-right wing, yet in many ways he's ultra-libertarian), he made military sci-fi a very notable genre too.
Robert E Howard has the very stuff of adventure flowing from his pages, the essence and panoply of a warrior on his way in the world can be found instantly with his works. No messing about either with the PC niceties entangling many writers these days, he's right down the bones of it and liberals can weep tears of oceans! LOL
Someone compared my work to Tolkein's LOTR but in a post-apocalyptic age. I'm not so sure about that entirely. Perhaps when I get the other books written and get a whole global conflict thing going (like Tolkein did with Middle-Earth in flames etc) then maybe I can explore that further...
