Jack London (1876–1916), born John Griffith Chaney, was an iconic American novelist, journalist, and social activist. Pioneering in the world of commercial magazine fiction, London was one of the first writers to gain worldwide celebrity and earn a large fortune from writing alone. His experiences as a prospector in the Klondike during the Gold Rush heavily influenced his literary work, underpinning his most famous novels 'The Call of the Wild' (1903) and 'White Fang' (1906). His writing style merged elements of naturalism, adventure, and social commentary, often exploring topics of survival, individualism, and the nature versus nurture debate. Another notable work, 'Hearts of Three' - lesser-known compared to his seminal novels - nonetheless showcases London's flair for adventure and romance. A prolific writer despite his short life, London published more than fifty books, including novels, memoirs, and collections of essays and short stories before his untimely death at the age of 40. His works are celebrated for their narrative vigor and are imprinted with his varied life experiences, including his time as a sailor, hobo, and gold prospector. London's prose elicits the harshness of nature and the struggles within human existence, earning him a distinguished place in American literature.
