John Griffith "Jack" London (born John Griffith Chaney; January 12, 1876 - November 22, 1916) was an American novelist, journalist, and social activist. 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.
Accusations of plagiarism
London was vulnerable to accusations of plagiarism, both because he was such a conspicuous, prolific, and successful writer and because of his methods of working. He wrote in a letter to Elwyn Hoffman, "expression, you see--with me--is far easier than invention." He purchased plots and novels from the young Sinclair Lewis and used incidents from newspaper clippings as writing material.  In July 1901, two pieces of fiction appeared within the same month: London's "Moon-Face", in the San Francisco Argonaut, and Frank Norris' "The Passing of Cock-eye Blacklock", in Century Magazine. Newspapers showed the similarities between the stories, which London said were "quite different in manner of treatment, [but] patently the same in foundation and motive." London explained both writers based their stories on the same newspaper account. A year later, it was discovered that Charles Forrest McLean had published a fictional story also based on the same incident.  Egerton Ryerson Young claimed The Call of the Wild (1903) was taken from Young's book My Dogs in the Northland (1902). London acknowledged using it as a source and claimed to have written a letter to Young thanking him.  In 1906, the New York World published "deadly parallel" columns showing eighteen passages from London's short story "Love of Life" side by side with similar passages from a nonfiction article by Augustus Biddle and J. K Macdonald, titled "Lost in the Land of the Midnight Sun".  London noted the World did not accuse him of "plagiarism", but only of "identity of time and situation", to which he defiantly "pled guilty".  The most serious charge of plagiarism was based on London's "The Bishop's Vision", Chapter 7 of his novel The Iron Heel (1908). The chapter is nearly identical to an ironic essay that Frank Harris published in 1901, titled "The Bishop of London and Public Morality". Harris was incensed and suggested he should receive 1/60th of the royalties from The Iron Heel, the disputed material constituting about that fraction of the whole novel. London insisted he had clipped a reprint of the article, which had appeared in an American newspaper, and believed it to be a genuine speech delivered by the Bishop of London.
