W. Ryerson Johnson (October 19, 1901 – May 24, 1995) is credited with authoring three Doc Savage novels: Land of Always-Night, The Fantastic Island, and The Motion Menace. For the last novel, Johnson supplied the idea for the story, but the novel was written by Lester Dent.
Alan Hathway, noted executive editor at Newsday, wrote four Doc Savage novels: The Devil’s Playground, The Headless Men, The Mindless Monsters, and The Rustling Death.
