(1880-1942) US writer whose slender output appeared primarily in Weird Tales. He first earned popular notice for his Science Fantasy "When the Green Star Waned" (1925) and its sequel, "The Oath of Hul Jok" (1928), but is best-known for a handful of romantic fantasies that embody his beliefs in Occultism. In "The Eternal Conflict" (1925) and "The Dark Lore" (1927) adventurers in the Astral Plane encounter the traditional Judeo-Christian Hell. "The Red Witch" (1932), "The Sapphire Goddess" (1934; vt "The Sapphire Siren"), "The Sea-Witch" (1937) and "The Heart of Atlantan" (1940) all feature Souls that transmigrate across Time or undergo Reincarnation to enact conflicts from the past.
