John Griffith "Jack" London (born John Griffith Chaney,[1] January 12, 1876 – November 22, 1916)[2][3][4][5] was an American author, journalist, and social activist. He was a pioneer in the then-burgeoning world of commercial magazine fiction and was one of the first fiction writers to obtain worldwide celebrity and a large fortune from his fiction alone.[6] 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".[citation needed] 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.

London was a passionate advocate of unionization, socialism, and the rights of workers and wrote several powerful works dealing with these topics such as his dystopian novel, The Iron Heel and his non-fiction exposé, The People of the Abyss.
