"The Vampyre" is a short story or novella written in 1819 by John William Polidori which is a progenitor of the romantic vampire genre of fantasy fiction. The tale was first published in book form by Sherwood, Neely, and Jones in London, Paternoster-Row, in 1819 in octavo as The Vampyre; A Tale in 84 pages. The notation on the cover noted that it was: "Entered at Stationers' Hall, March 27, 1819". Initially, the author was given as Lord Byron. Later printings removed Byron's name and added Polidori's name to the title page.
John William Polidori (7 September 1795 - 24 August 1821) was an English writer and physician of Italian descent. He is known for his associations with the Romantic movement and credited by some as the creator of the vampire genre of fantasy fiction. His most successful work was the 1819 short story, The Vampyre, one of the first vampire stories in English. Although originally and erroneously accredited to Lord Byron, both Byron and Polidori affirmed that the story is Polidori's.
