Mary Wollstonecraft Shelley

Mary Shelley was born in London in 1797, the daughter of William Godwin and Mary Wollstonecraft, two radical writers. Her mother died when she was only ten days old.  In 1816 she married Percy Bysshe Shelley, then unknown, and they lived in Italy until Shelley's death in 1822. The idea for Frankenstein came to her when she was staying on Lake Geneva in 1816 but was not published for two years.  She wrote several other novels and contributed to the Westminster Review.   She died in February 1851."
It is quite difficult to believe that a young girl of 18 years old would be the author of a book that would become the first monster film, creation film, bionic film, horror film, publicly banned film, and the first of many Frankenstein films. But we must give this young girl credit for her literary talent and active imagination. Mary Shelley is responsible for many fine literary works of art but none are as famous as Frankenstein or The Modern Prometheus published in 1818. The tale Shelley tells is of a young Dr. Frankenstein who tries to create a living being but instead creates a monster.
