The most well-known work in this genre is of course Bram Stoker's gothic novel Dracula. It was not, however, the first. Myths and legends of blood-imbibing creatures capable of transmogrification predate the novel form. The immediate antecedent of Dracula is Sheridan le Fanu's classic of the genre, Carmilla. This in turn owes more than a little to John William Polidori's The Vampyre; this work was contemporaneous to Lord Byron's poem The Giaour which also treats on this subject.
More recent proponent of this school of fiction include Richard Matheson and Anne Rice.
