The Year without a Summer caused Mary Shelly and her literary friends to hole up indoors during their Swiss vacation. To pass the time, they took drugs (laudanum) and told stories. Later, they published them. Shelly’s Frankenstein, or The Modern Prometheus.
Frankenstein’s monster wasn’t the only classic horror monster that came into being at that gathering. In fact, a character that, for literary purposes, is Dracula’s father got invented.
The character’s name was Lord Ruthven, and he was modelled off the notorious British aristocrat, Lord Byron. (Remember Byron. Remember Byron.)
An employee of Byron’s, John Polidori, wrote the story titled, The Vampyre and modelled the character after his master, while the two were on a trip in Europe (just like two characters in the story) and were stopped at the Swiss literary gathering by the Year without a Summer. (Strange how it all connects, ain’t it?)
The reason Lord Ruthven can be described as Dracula’s father is that, while there had been vampires before, both in the legends of Europe and other places, they were pictured as brutish, repulsive monsters, not the suave, debonaire romantic types that have dominated vampire fiction since.
So it’s interesting . . . the Year without a Summer ended up getting both Bela Lugosi and Boris Karloff the jobs that made them famous, 120 years later.
