English-Italian writer, physician, son of Gaetano Polidori and uncle to Dante Gabriel and Christina Rossetti. Some consider John Polidori as the creator of modern vampire fiction with his work "The Vampyre." John Polidori was Lord Byron's personal physician and participated in the famous ghost story competition in Geneva which resulted in Mary Shelley's Frankenstein. Inadequately financially supported by his writing or medical career and suffering from debt and depression, Polidori committed suicide in 1821.
