Goodwin, "Hal Goodwin" and "Harold Leland Goodwin." He also wrote children's books as Blake Savage (Rip Foster Rides the Gray Planet) and John Blaine (the Rick Brant series). In the latter case, he co-wrote (with Peter J. Harkins) the first 3 books in the series and wrote books 4 through 24 by himself. In 1947, he wrote The Feathered Cape, a boy's adventure novel set in Hawaii. It was based on events leading up to the Battle of the Nu'uanu Valley (1795) in the war for Hawaiian unification.
