The captain in Mary Shelley's "Frankenstein" is named Robert Walton. He is an ambitious explorer leading an expedition to the North Pole and serves as the frame narrator for the novel, documenting his encounters with Victor Frankenstein. Walton's correspondence with his sister and his interactions with Frankenstein provide insight into the themes of ambition and the quest for knowledge.
The Captain's gloominess makes the stranger gloomy too.
There are actually three narrators in Mary Shelly's "Frankenstein." Captain Walton on the outside, Victor Frankenstein on the inside, and the monster in isolated incidents.
