Horror:

Horror is fiction that involves a sinister atmosphere and supernatural characters and settings. It includes stories of witches, vampires, and monsters.

H.P Lovecraft:

Howard Phillips Lovecraft (August 20, 1890 – March 15, 1937) — known as H. P. Lovecraft — was an American author of horror, fantasy andscience fiction, especially the subgenre known as weird fiction.^[1]

Lovecraft's guiding aesthetic and philosophical principle was what he termed "cosmicism" or "cosmic horror", the idea that life is incomprehensible to human minds and that the universe is fundamentally inimical to the interests of humankind. As such, his stories express a profound indifference to human beliefs and affairs. Lovecraft is best known for his Cthulhu Mythos story cycle and the Necronomicon, a fictional grimoire of magical rites and forbidden lore.^[2]

Although Lovecraft's readership was limited during his lifetime, his reputation has grown over the decades, and he is now regarded as one of the most influential horror writers of the 20th century. According to Joyce Carol Oates, Lovecraft—as with Edgar Allan Poe in the 19th century—has exerted "an incalculable influence on succeeding generations of writers of horror fiction".^[3] Stephen King called Lovecraft "the twentieth century's greatest practitioner of the classic horror tale."

Robert Louis Stevenson:

Robert Louis Balfour Stevenson (13 November 1850 – 3 December 1894) was a Scottish novelist, poet, essayist, and travel writer. His most famous works are Treasure Island, Kidnapped, and Strange Case of Dr Jekyll and Mr Hyde.

A literary celebrity during his lifetime, Stevenson now ranks among the 26 most translated authors in the world.^[3] His works have been admired by many other writers, including Jorge Luis Borges, Ernest Hemingway, Rudyard Kipling, Marcel Schwob, Vladimir Nabokov,^[4] J. M. Barrie,^[5] and G. K. Chesterton, who said of him that he "seemed to pick the right word up on the point of his pen, like a man playing spillikins."^[6]

Bram Stoker:

Abraham "Bram" Stoker (8 November 1847 – 20 April 1912) was an Irish novelist and short story writer, best known today for his 1897 Gothic novelDracula. During his lifetime, he was better known as personal assistant of actor Henry Irving and business manager of the Lyceum Theatre in London, which Irving owned.
