Mary Shelly wasn't a scientist. Another aside: the publisher of the first edition of Marlow's 'Faustus' had a woodcut made up for the title page. He also published it on broadside ballads, where the printed matter was deleted. It was passed on to subsequent printers, and can be seen throughout the 17th century. A rival printer, c 1680, who didn't have access to it, commissioned a copy, but it wasn't terribly good and is easily spotted as an imitation.
