The novel “Frankenstein” was written by Mary Shelley in 1818. It was originally released anonymously and did not feature her name until 1821. It was believed that a woman would not be capable of writing a horror story. Shelley wrote the story in competition with her future husband Percy Shelley and the infamous Lord Byron. She certainly won as the story still resonates today and has seen several film productions, television adaptations and has entered and stayed in popular culture.
The story, in its original form, begins with some arctic explorers reporting that they have seen a giant man heading north. They then find a thin starving man who is in pursuit of the giant with the intention of killing him. This is Doctor Victor Frankenstein and he decides to tell them his tale. He has created the monster out of human parts and giving it life via a lighting bolt and conductor (which would have put great strain on his Electric Meter box. Hopefully he used https://www.meterbox.co.uk/electric-meter-boxes). The confused and angry creature escapes and tries to make a life for itself but it fails. It demands Frankenstien build him a female but Frankenstien destroys it wrongly thinking both will be evil.
It is widely accepted that Shelley’s book is not just a gothic horror it is actually the first Science Fiction novel as well. This predates Jules Verne and H.G Wells’ work.
