John William Polidori 
The Diary of Dr. John William Polidori — 1816 — Relating to Byron, Shelley, Etc. Edited and Elucidated by William Michael Rossetti [EPUB ebook] 

First published in 1911, this vintage book contains extracts from the diary of John William Polidori, and chiefly those parts relating to his relationships with Byron, Shelley, and others of the Romantic movement. John William Polidori (7 September 1795 – 24 August 1821) was an English writer and physician famous for his associations with the Romantic movement and for being, as many maintain, the creator of the vampire genre of fantasy fiction. His most notable work was the short story ‘The Vampyre’ (1819). This volume will appeal to those with an interest in the life of Polidori and especially those who he associated with, namely Lord Byron and Percy Bysshe Shelley. Other notable works by this author include: “Cajetan” (1816), “Boadicea” (1816), and “On the Punishment of Death” (1816). Many vintage books such as this are increasingly scarce and expensive. It is with this in mind that we are republishing this volume now in an affordable, modern, high-quality edition complete with a specially-commissioned new introduction of the author.
