James Oliver "Jim" Curwood (June 12, 1878 – August 13, 1927) was an American action-adventure writer and conservationist.
His books were often based on adventures set in the Yukon or Alaska and ranked among the top-ten best sellers in the United States in the early 1920s, according to Publishers Weekly.
At least eighteen motion pictures have been based on or directly inspired by his novels and short stories; one was produced in three versions from 1919 to 1953.
At the time of his death, Curwood was the highest paid (per word) author in the world.
He built Curwood Castle as his residence in his hometown of Owosso, Michigan, and used one turret as his writing studio.
The mansion was listed on the National Register of Historic Places and is now operated as a museum.
The city commemorates him with an annual Curwood Festival.
