Which famous novelist was given the name John Griffith Chaney at birth?

Jack London (born John Griffith Chaney; January 12, 1876 – November 22, 1916) was an American novelist, journalist, and social activist. A pioneer of commercial fiction and American magazines, he was one of the first American authors to become an international celebrity and earn a large fortune from writing. He was also an innovator in the genre that would later become known as science fiction.

On July 12, 1897, London (age 21) 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.

He concluded that his only hope of escaping the work "trap" was to get an education and "sell his brains". He saw his writing as a business, his ticket out of poverty, and, he hoped, a means of beating the wealthy at their own game. On returning to California in 1898, London began working to get published, a struggle described in his novel, "Martin Eden" (serialized in 1908, published in 1909).
