The writer Mary Shelley was the spouse of the poet Percy Shelley. Mary Wollstonecraft Shelley (née 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. In 1814, Mary began a romance with one of her father's political followers, Percy Bysshe Shelley, who was already married. Together with Mary's stepsister Claire Clairmont, Mary and Shelley 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. They married in late 1816, after the suicide of Percy Shelley's first wife, Harriet.
