What is the name of the protagonist in Mary Shelley's 'Frankenstein'?

The protagonist in Mary Shelley's 'Frankenstein' is Victor Frankenstein.

Victor is a young scientist from Geneva who becomes obsessed with discovering the secret of life. While studying at the University of Ingolstadt, he assembles a body from human remains and succeeds in animating it. Horrified by the creature's appearance, he abandons it almost immediately, setting the novel's tragedy in motion.

A common mistake is calling the creature itself “Frankenstein.” In Shelley's novel, Frankenstein is the creator's surname; the unnamed being is described as Victor's creature, monster, or daemon. Victor is also the novel's central character, although the story is framed through letters written by the explorer Robert Walton. Victor recounts his history to Walton while being pursued across the Arctic by his creation.

The character reflects the novel's subtitle, 'The Modern Prometheus': like the mythological Prometheus, Victor reaches beyond ordinary human limits and suffers for doing so. His scientific ambition, guilt, and failure to take responsibility drive the book's Gothic and philosophical drama.
