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 river Rhine in Germany, and stopping in Gernsheim, 17 kilometres (11 mi) away from 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.
