Shelley, Mary Wollstonecraft, 1797–1851, English author; daughter of William Godwin and Mary Wollstonecraft. In 1814 she fell in love with the poet Percy Bysshe Shelley, accompanied him abroad, and after the death of his first wife in 1816 was married to him. Her most notable contribution to literature is her novel of terror, Frankenstein, published in 1818. It is the story of a German student who learns the secret of infusing life into inanimate matter and creates a monster that ultimately destroys him. Included among her other novels are Valperga (1823), The Last Man (1826), and the partly autobiographical Lodore (1835). After Shelley's death in 1822, she devoted herself to caring for her aged father and educating her only surviving child, Percy Florence Shelley. In 1839–40 she edited her husband's works.
