Thomas Clark Hinkle, (June 12, 1876 - May 13, 1949) was an American novelist. He went to high school in Junction City, Kansas. In 1904 he graduated as a medical doctor from the University of Kansas. In 1908 he married Roxana E. Stevens and together they raised two children. He began writing in the 1920s in a mix of juvenile and western fiction. He specialized in writing stories about horses and dogs. Kirkus Review commented that Hinkle had an overly sentimental view of horses and animals in general . His stories of horses are all about the American west, some based on true narratives but almost always with the theme ‘wild horse can only be mastered by one man’.
