Jack London is not only one of the most significant storytellers in American literary history, but he was also one of the most commercially successful. As a competent marketing strategist and relentless businessman, he conquered the American literary market at the beginning of this century, primarily through the publication of his works in magazines such as the Saturday Evening Post and Cosmopolitan, becoming one of the most colorful figures in public life. The numerous biographies, autobiographically influenced novels, and especially the extensive correspondence not only paint a vivid picture of an evolving industry but also highlight the tragedy of an artist increasingly alienated from his work under the constant pressure of economic constraints.
