Frankenstein; or, The Modern Prometheus is an 1818 Gothic novel written by English author Mary Shelley. Frankenstein tells the story of Victor Frankenstein, a young scientist who creates a sapient creature in an unorthodox scientific experiment. Shelley started writing the story when she was 18, and the first edition was published anonymously in London on 1 January 1818, when she was 20. Her name first appeared in the second edition, which was published in Paris in 1821. Shelley travelled through Europe in 1815, moving along the Rhine in Germany, and at one point stopping in Gernsheim, near Frankenstein Castle, where, about a century earlier, Johann Konrad Dippel, an alchemist, had engaged in experiments. She then journeyed to the region of Geneva, Switzerland, where much of the story takes place. Galvanism and occult ideas were topics of conversation for her companions, particularly for her lover and future husband Percy Bysshe Shelley. In 1816, Mary, Percy, John Polidori, and Lord Byron had a competition to see who wrote the best horror story. After thinking for days, Shelley was inspired to write write Frankenstein after imagining a scientist who created life and was horrified by what he had made. Frankenstein is one of the most well-known works of English literature. Infused with elements of the Gothic novel and the Romantic movement, it has had a considerable influence on literature and on popular culture, spawning a complete genre of horror stories, films, and plays.
