Iliff David "Rich" Richardson (April 9, 1918 – October 10, 2001) was simultaneously a US Navy ensign and a US Army major while fighting with the Philippine resistance against Japan during World War II. He recounted his exploits to author Ira Wolfert, who published them in the book American Guerrilla in the Philippines in 1945. A character based on Richardson was played by Tyrone Power in the 1950 film of the same name.
