John Everson (born March 14, 1966) is an American author of contemporary horror, dark fantasy, science fiction and fantasy fiction.
 He is the author of eight novels and four short fiction collections, as well as three mini-collections, all focusing on horror and the supernatural.
 His novel "Covenant", was originally released in a limited edition hardcover by Delirium Books in 2004 and won the Bram Stoker Award for a First Novel the following year from the Horror Writers Association.
 His sixth novel, "NightWhere", was a finalist for the Bram Stoker Award in 2012.
Dracula is an 1897 Gothic horror novel by Irish author Bram Stoker.
 It introduced Count Dracula, and established many conventions of subsequent vampire fantasy.
 The novel tells the story of Dracula's attempt to move from Transylvania to England so that he may find new blood and spread the undead curse, and of the battle between Dracula and a small group of men and a woman led by Professor Abraham Van Helsing.
Dracula is a fictional supervillain appearing in American comic books published by Marvel Comics.
 He is based on the vampire Count Dracula from the novel of the same name by author Bram Stoker.
Bram Stoker's Legend of the Mummy, or simply Bram Stoker's The Mummy, is a horror-fantasy 1998 film based on Bram Stoker's novel "The Jewel of Seven Stars".
 It features an ensemble cast including Academy Award Winner Louis Gossett, Jr., Eric Lutes, Amy Locane, Lloyd Bochner, Victoria Tennant, Mary Jo Catlett, Aubrey Morris, and Richard Karn.
 Morris previously played Dr. Putnum in "Blood from the Mummy's Tomb", the Hammer adaptation of the same novel.
Commander Henry Hugh Gordon Dacre Stoker, DSO (2 February 1885 – 2 February 1966), commonly credited in films as H. G. Stoker or Dacre Stoker, was a Royal Navy officer of the First and Second World Wars, and a stage and screen actor.
 He was also a sportsman, active in polo, croquet, hurling and tennis, competing at Wimbledon and becoming the croquet champion of Ireland in 1962, aged 77.
 He was a cousin to the author Bram Stoker.
Bran Castle (Romanian: "Castelul Bran" ; German: "Törzburg" ; Hungarian: "Törcsvár" ), situated near Bran and in the immediate vicinity of Brașov, is a national monument and landmark in Romania.
 The fortress is situated on the border between Transylvania and Wallachia, on DN73.
 Commonly known as "Dracula's Crib" (although it is one among several locations linked to the Dracula legend, including Poenari Castle and Hunyad Castle), it is often erroneously referred to as the home of the title character in Bram Stoker's "Dracula".
 There is, however, no evidence that Stoker knew anything about this castle, which has only tangential associations with Vlad the Impaler, voivode of Wallachia, the putative inspiration for Dracula.
 As discovered by the Dutch author Hans Corneel de Roos, the location Bram Stoker actually had in mind for Castle Dracula while writing his novel was an empty mountain top, Mount Izvorul Călimanului, 2033 m high, located in the Călimani Alps near the former border with Moldavia.
 Stoker's description of Dracula's crumbling fictional castle also bears no resemblance to Bran Castle.
Linda D. Addison (born September 8, 1952) is an American poet and writer of horror, fantasy, and science fiction.
 Addison is the first African-American winner of the Bram Stoker Award, which she won four times.
 The first two awards were for her poetry collections "Consumed, Reduced to Beautiful Grey Ashes" (2001) and "Being Full of Light, Insubstantial" (2007).
 Her poetry and fiction collection "How To Recognize A Demon Has Become Your Friend" won the 2011 Bram Stoker Award for Superior Achievement in a Poetry Collection.
 She received a fourth HWA Bram Stoker for the collection "The Four Elements", written with Marge Simon, Rain Graves, and Charlee Jacob.
 Addison is a founding member of the CITH (Circles in the Hair) writing group.
Bram Stoker's Dracula's Curse (also known simply as Dracula's Curse) is a 2006 horror film by The Asylum, written and directed by Leigh Scott.
 Despite featuring Bram Stoker's name in the title, the film is not directly based on any of his writings or a mockbuster to the 1992 film "Bram Stoker's Dracula", but shares similarities to films such as "", "Dracula 2000", "" and "Van Helsing".
 The film also shares some similarities with the 1971 Hammer horror film "Countess Dracula", which also features a Dracula-esque femme fatale in the lead role.
Abraham "Bram" Stoker (8 November 1847 – 20 April 1912) was an Irish author, best known today for his 1897 Gothic novel "Dracula".
 During his lifetime, he was better known as the personal assistant of actor Henry Irving and business manager of the Lyceum Theatre in London, which Irving owned.
Gothic fiction, which is largely known by the subgenre of Gothic horror, is a genre or mode of literature and film that combines fiction and horror, death, and at times romance.
 Its origin is attributed to English author Horace Walpole, with his 1764 novel "The Castle of Otranto", subtitled (in its second edition) "A Gothic Story".
 The effect of Gothic fiction feeds on a pleasing sort of terror, an extension of Romantic literary pleasures that were relatively new at the time of Walpole's novel.
 It originated in England in the second half of the 18th century where, following Walpole, it was further developed by Clara Reeve, Ann Radcliffe, William Thomas Beckford and Matthew Lewis.
 The genre had much success in the 19th century, as witnessed by Mary Shelley's "Frankenstein" and the works of Edgar Allan Poe.
 Another well known novel in this genre, dating from the late Victorian era, is Bram Stoker's "Dracula".
 The name "Gothic" refers to the (pseudo)-medieval buildings, emulating Gothic architecture, in which many of these stories take place.
 This extreme form of romanticism was very popular in England and Germany.
 The English Gothic novel also led to new novel types such as the German "Schauerroman" and the French "Georgia".
