John Griffith "Jack" London (born John Griffith Chaney, January 12, 1876 – November 22, 1916). He is best remembered as the author of White Fang and Call of the Wild, set in the Klondike Gold Rush, as well as the short stories "To Build a Fire", "An Odyssey of the North", and "Love of Life". He also wrote of the South Pacific in such stories as "The Pearls of Parlay" and "The Heathen", and of the San Francisco Bay area in The Sea Wolf.

Jack London was born in San Francisco of an unmarried mother of wealthy background, Flora Wellman. His father may have been William Chaney, a journalist, lawyer, and major figure in the development of American astrology. Because Flora was ill, Jack was raised through infancy by an ex-slave, Virginia Prentiss, who would remain a major maternal figure while the boy grew up. Late in 1876, Flora married John London, a partially disabled Civil War veteran. The family moved around the Bay area before settling in Oakland, where Jack completed grade school. Though the family was working class, it was not so impoverished as London's later accounts claimed. 

Jack London Credo

London's literary executor, Irving Shepard, quoted a "Jack London Credo" in an introduction to a 1956 collection of London stories:
 
I would rather be ashes than dust!
I would rather that my spark should burn out in a brilliant blaze than it should be stifled by dry-rot.
I would rather be a superb meteor, every atom of me in magnificent glow, than a sleepy and permanent planet.
The function of man is to live, not to exist.
I shall not waste my days trying to prolong them.
I shall use my time.
