On July 12, 1897, London (age 21) and his sister's husband Captain Shepard sailed to join the Klondike Gold Rush. This was the setting for some of his first successful stories. London's time in the harsh Klondike, however, was detrimental to his health. Like so many other men who were malnourished in the goldfields, London developed scurvy. His gums became swollen, leading to the loss of his four front teeth. A constant gnawing pain affected his hip and leg muscles, and his face was stricken with marks that always reminded him of the struggles he faced in the Klondike. Father William Judge, "The Saint of Dawson", had a facility in Dawson that provided shelter, food and any available medicine to London and others. His struggles there inspired London's short story, "To Build a Fire" (1902, revised in 1908), which many critics assess as his best.
