John William Polidori (7 September 1795 – 24 August 1821) was an English writer and physician. 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 short story "The Vampyre" (1819), the first published modern vampire story. Although originally and erroneously accredited to Lord Byron, both Byron and Polidori affirmed that the story is Polidori's.
