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 1819 short story, The Vampyre, one of the first vampire stories in English. (wikipedia)
The charismatic and sophisticated vampire of modern fiction was born in 1819 with the publication of The Vampyre by John Polidori. The story was highly successful and arguably the most influential vampire work of the early 19th century and it is a progenitor of the romantic vampire genre of fantasy fiction so popular today.
