Mary Shelley was raised by her philosopher father William Godwin and was interested in political theories from a young age. She is most famous for her 1818 novel Frankenstein, which tells the story of Victor Frankenstein who creates a sapient creature through scientific experimentation. The creature is rejected by Victor and society, driving him to seek revenge. The novel examines themes of the dangers of unchecked scientific progress, morality, and what makes someone human. It is considered one of the earliest works of science fiction.
