Both novels are written by Jack London (1876 -1916), an American novelist, journalist, and social activist. He was raised by his mother and his stepfather, whose surname he took. A pioneer in the world of commercial magazine fiction, he was one of the first writers to become a worldwide celebrity and earn a large fortune from writing. He was also an innovator in the genre that would later become known as science fiction.

"The Call of the Wild" (published in 1903) and "White Fang" ( published in 1906) are his most famous works. They depict elemental struggles for survival. "The Call of the Wild" tells the story of Buck, a domestic dog who is kidnapped from his home in California and forced to pull sleds in the Arctic wasteland. "White Fang", by contrast, is the tale of a crossbreed who is a three-quarters wolf and a quarter dog, and who must endure considerable suffering in the wilderness before being tamed by an American and taken to live in California.

During the 20th century, he was one of the most extensively translated American authors.

Although he became the highest-paid writer in the United States at that time, his earnings never matched his expenditures, and he was never freed of the urgency of writing for money.
