Richard Brinsley Peake (19 February 1792 – 4 October 1847) was a dramatist of the early 19nth century best remembered today for his 1823 play Presumption; or, the Fate of Frankenstein, a work based on the novel Frankenstein or the Modern Prometheus by Mary Shelley. It was Peake, not Shelley, who wrote the famous line, "It lives!" Peake created the character of Fritz (later rechristened Igor in popular culture), who has no analog in the original novel.
