Jack London (1876-1916) was one of the most popular and influential American writers of the early twentieth century. Novelist, journalist, war correspondent, sailor, adventurer, and political activist, London drew heavily upon his extraordinary life experiences to create works marked by realism, intensity, and psychological insight.His best-known novels-including The Call of the Wild, White Fang, Martin Eden, and The Sea-Wolf-helped establish him as a major figure in American literature. London's nonfiction and autobiographical works, including John Barleycorn, revealed a more introspective and philosophical side of his writing, exploring themes of survival, class, identity, addiction, and the human struggle against both society and nature.
