Mary Wollstonecraft Shelley was an English novelist who wrote the Gothic novel Frankenstein; or, The Modern Prometheus (1818), which is considered an early example of science fiction. She also edited and promoted the works of her husband, the Romantic poet and philosopher Percy Bysshe Shelley. Her father was the political philosopher William Godwin and her mother was the philosopher and women's rights advocate Mary Wollstonecraft.
Mary's mother died 11 days after giving birth to her. She was raised by her father, who provided her with a rich informal education, encouraging her to adhere to his own anarchist political theories. When she was four, her father married a neighbour, Mary Jane Clairmont, with whom Mary had a troubled relationship.
In 1814, Mary began a romance with one of her father's political followers, Percy Bysshe Shelley, who was already married. Together with her stepsister, Claire Clairmont, she and Percy left for France and travelled through Europe. Upon their return to England, Mary was pregnant with Percy's child. Over the next two years, she and Percy faced ostracism, constant debt and the death of their prematurely born daughter.
