Jack London (1876-1916) spent his youth on the waters of the San Francisco Bay. In 1897, when gold was discovered in the Klondike, he obtained a grubstake and spent a freezing, fruitless winter in the Far North; by spring he was ready to return home to write. In 1900, his collection of short stories Son of the Wolf was published. Two more volumes of Yukon short stories, a juvenile novel, and a Klondike novel followed in rapid succession. Then came his bestselling novel The Call of the Wild (1903) and the beginning of the years that were to bring him wealth and worldwide popularity. The eternal traveler, London served as a correspondent in Japan and Mexico and sailed his own ketch to the Solomon Islands before his death.
