Mary Shelley (née Mary Wollstonecraft Godwin; 30 August 1797 – 1 February 1851) was an English novelist, short story writer, dramatist, essayist, biographer, and travel writer, best known for her Gothic novel Frankenstein: or, The Modern Prometheus (1818). 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 feminist Mary Wollstonecraft.
After Mary Godwin's mother died giving birth to her, she and her older half-sister, Fanny Imlay, were raised by her father. When Mary was three, Godwin married his neighbour, Mary Jane Clairmont. Godwin provided his daughter with a rich, if informal, education, encouraging her to adhere to his liberal political theories. In 1814, Mary Godwin fell in love with one of her father’s political followers, the married Percy Bysshe Shelley. Together with Mary's stepsister, Claire Clairmont, they left for France and travelled through Europe; upon their return to England, Mary was pregnant. Over the next two years, she and Percy faced ostracism, constant debt, and the death of their prematurely born daughter. They married in late 1816 after the suicide of Percy Shelley's first wife, Harriet.
