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. The oldest son of Gaetano Polidori, an Italian political émigré scholar, and Anna Maria Pierce, an English governess. He had three brothers and four sisters. His sister, Frances Polidori, married exiled Italian scholar Gabriele Rossetti, and thus John, posthumously, became the uncle of Maria Francesca Rossetti, Dante Gabriel Rossetti, William Michael Rossetti, and Christina Georgina Rossetti. William Michael Rossetti published Polidori's journal in 1911. Less
