Horror? Yeah I guess the old sci fi was pretty spooky. My favorite authors were Roger Zelazny (Lord of Light, Amber), Larry Niven (Ringworld), Harry Harrison (everything he wrote, Deathworld, Stainless Steel Rat, etc), Gordon Dickson(everything he wrote that I could get hands on), Isaac Asimov, Ray Bradbury(dry stories, but lots of horror), Orson Scott Card( even the ones now out of print), Heinlein(grok to the all of them), Arthur C Clarke, C.J. Cherryh (Faded Sun), Peter F Hamilton (Pandoras Star),Stephen R Donaldson, some of these, I am missing quite a few here, but the books written 1950's thru 1980's I read voraciously, George R R Martin, some of Ursula K LeGuin. I mourn the loss of many I can no longer find, NO, Stephen King began a new genre of writers that were too predictable in format for me to have patience with - they were all alike - every single story was alike each of his others, I blamed it on his computer and writing programs, but I lost patience with each and every one of them after I read 3 or 4.
