Whose Novel Introduced Frankenstein?

Mary Shelley wrote Frankenstein at just 18 years old during the famous summer of 1816 at Lake Geneva, where Lord Byron challenged his guests to write ghost stories. Published anonymously in 1818, the novel tells of Victor Frankenstein, a scientist who creates a sentient creature from dead tissue. It is widely considered the first true science fiction novel and raises enduring questions about scientific responsibility, creation, and humanity. Shelley was 20 when the first edition appeared; her authorship was revealed in the 1823 second edition.
