Jack London, born John Griffith Chaney on January 12, 1876, in San Francisco, California, was an American novelist, journalist, and social activist. He is best known for his adventure novels "The Call of the Wild" and "White Fang," both of which explore the themes of survival and the law of the jungle in the harsh environment of the Klondike Gold Rush. London's life was as adventurous as his stories. He traveled extensively, lived in Hawaii, and engaged in numerous physical pursuits, which ultimately led to his health decline. He died on November 22, 1916, at his ranch in Glen Ellen, California, from kidney failure at the age of 40. Despite his short life, London's impact on literature, especially in portraying the natural world and human nature, remains significant. His works have been translated into many languages and continue to be popular for their vivid storytelling and exploration of human spirit and endurance.
