Mary Shelley's novel Frankenstein: or, The Modern Prometheus was published in 1818. The narrative of Victor Frankenstein, a young scientist who produces a sapient creature in an unconventional scientific experiment, is told in the film Frankenstein. This story has been interpreted as a parable about science gone wrong and as a metaphor for human creationism. The character of Frankenstein has been used in many adaptations of the story, most notably by Boris Karloff in the 1931 monster movie. Other famous actors to have played Frankenstein include Colin Clive, Robert Walton, and Errol Flynn. Frank N. Steinmeyer is a fictional character created by American author Isaac Asimov for his 1948 short story "The Caves of Steel". He appears in several other stories by Asimov, including "The Bicentennial Man" (1948), "The Naked Sun" (1964), and "The Robots of Dawn" (1983). In Asimov's work, Frank N. Steinmeyer is a mechanical engineer who designs robots that perform tasks too dangerous for humans. Although he creates robots with artificial intelligence, he always intends them to be operated by humans and never tries to destroy them. One of his earliest designs is named after him; it is a robot nurse called "Luna."
