Jack London's work was deeply informed by his life of adventure as a sailor, gold prospector in the Klondike, and war correspondent. He is best known for his tales of survival and the struggle against nature, including The Call of the Wild and White Fang. A committed socialist, his writing often reflected his political views and his belief in social Darwinism. He was one of the first American writers to achieve international celebrity and a large fortune through his fiction, leaving behind a prolific body of work that continues to inspire adventure readers today.
