Best known for his adventure fiction novels, Jack London was also a passionate advocate for the rights of workers and social reform, writing several powerful works dealing with. Jack London, pseudonym of John Griffith Chaney, American novelist and short-story writer whose best-known works--among them The Call of the Wild (1903) and White Fang (1906)--depict elemental struggles for survival. During the 20th century he was one of the most extensively translated of American authors. Deserted by his father, a roving astrologer, he was raised in Oakland, California, by his spiritualist mother and his stepfather, whose surname, London, he took. At age 14 he quit school to escape poverty and gain adventure. He explored San Francisco Bay in his sloop, alternately stealing oysters or working for the government fish patrol. He went to Japan as a sailor and saw much of the United States as a hobo riding freight trains and as a member of Charles T. Kelly's industrial army (one of the many protest armies of the unemployed, like Coxey's Army, that was born of the financial panic of 1893). London saw depression conditions, was jailed for vagrancy, and in 1894 became a militant socialist. London educated himself at public libraries with the writings of Charles Darwin, Karl Marx, and Friedrich Nietzsche, usually in popularized forms. At 19 he crammed a four-year high school course into one year and entered the University of California, Berkeley, but after a year he quit school to seek a fortune in the Klondike gold rush. Returning the next year, still poor and unable to find work, he decided to earn a living as a writer. London studied magazines and then set himself a daily schedule of producing sonnets, ballads, jokes, anecdotes, adventure stories, or horror stories, steadily increasing his output. The optimism and energy with which he attacked his task are best conveyed in his autobiographical novel Martin Eden (1909). Within two years, stories of his Alaskan adventures began to win acceptance for their fresh subject matter and virile force. His first book, The Son of the Wolf: Tales of the Far North (1900), a collection of short stories that he had previously published in magazines, gained a wide audience. During the remainder of his life, London wrote and published steadily, completing some 50 books of fiction and nonfiction in 17 years. Although he became the highest-paid writer in the United States at that time, his earnings never matched his expenditures, and he was never freed of the urgency of writing for money. He sailed a ketch to the South Pacific, telling of his adventures in The Cruise of the Snark (1911). In 1910 he settled on a ranch near Glen Ellen, California, where he built his grandiose Wolf House. He maintained his socialist beliefs almost to the end of his life. Jack London's output, typically hastily written, is of uneven literary quality, though his highly romanticized stories of adventure can be compulsively readable. His Alaskan novels The Call of the Wild (1903), White Fang (1906), and Burning Daylight (1910), in which he dramatized in turn atavism, adaptability, and the appeal of the wilderness, are outstanding. His short story "To Build a Fire" (1908), set in the Klondike, is a masterly depiction of humankind's inability to overcome nature; it was reprinted in 1910 in the short-story collection Lost Face, one of many such volumes that London published.
