James Oliver "Jim" Curwood (1878 - 1927) was an American action-adventure writer and conservationist. His books ranked among Publisher's Weekly top-ten best sellers in the United States in the early 1920s. At least eighteen motion pictures have been based on or directly inspired by his novels and short stories. At the time of his death, he was the highest paid (per word) author in the world. His writing studio, Curwood Castle, is now a museum in Owosso, Michigan. His most successful work was his 1920 novel, The River's End. The book sold more than 100,000 copies and was the fourth best-selling title of the year in the United States, according to Publisher's Weekly.
