Victor Frankenstein is a fictional character and the main protagonist and title character in Mary Shelley's 1818 novel, Frankenstein; or, The Modern Prometheus. He is an Italian-Swiss scientist (born in Naples, Italy) who, after studying chemical processes and the decay of living things, gains an insight into the creation of life and gives life to his own creature (often referred to as Frankenstein's monster, or often colloquially referred to as simply "Frankenstein"). Victor later regrets meddling with nature through his creation, as he inadvertently endangers his own life and the lives of his family and friends when the creature seeks revenge against him. He is first introduced in the novel when he is seeking to catch the monster near the North Pole and is saved from near death by Robert Walton and his crew.

Some aspects of the character are believed to have been inspired by 17th-century alchemist Johann Konrad Dippel. Certainly, the author and people in her environment were aware of the experiment on electricity and dead tissues by Luigi Galvani and his nephew Antonio Aldini and the work of Alessandro Volta at the University of Pavia.
