Chapter 1: The Forgotten Half of the Invention
The detective story that Poe invented with The Murders in the Rue Morgue has received appropriate recognition. The science fiction stories he wrote in the same period have received considerably less, partly because they don't fit the dominant image of Poe as a Gothic horror writer and partly because the science fiction genre traces its official lineage through Jules Verne and H.G. Wells rather than back to its actual origin.
Poe's science fiction stories — including The Unparalleled Adventure of One Hans Pfaall (1835), The Balloon Hoax (1844), Mesmeric Revelation (1844), The Facts in the Case of M. Valdemar (1845), and several others — share a distinctive structure: they present speculative or fantastical events with the apparatus of factual credibility, using the rhetoric of scientific or journalistic reporting to make the implausible seem plausible.
This is precisely the structure of science fiction as Jules Verne and H.G. Wells would develop it. The difference between Gothic fantasy and science fiction is not the strangeness of the events but the mode of their presentation: Gothic fantasy invokes the supernatural without apology; science fiction presents the extraordinary as an extension of the possible, using the language of science and reason.
Verne acknowledged Poe. Wells acknowledged Poe. The acknowledgments have not stuck to the popular understanding of Poe's contribution.
