>Koji Suzuki
>Richard Matheson
>Robert W. Chambers
>Ray Bradbury
>Sheridan Le Fanu
>Clive Barker

These are generally the most well known authors that people typically associate with horror although someone like Ray Bradbury is more often associated with sci-fi but he wrote a lot of horror stuff too just none that are as well known as Fahrenheit.
