HP Lovecraft (1890 - 1937)
Great story teller. Go get one of his works. He is awesome in telling horror stories. No, he doesn't do ghosts, he does other things that are more chaotic and dark and mysterious. Notice the tentacles behind lurking him.
Also, notice that I used present tense.
He is still alive in our minds.
I will update more on his works and synopsis soon, including some bizarre pictures.
