William Scott-Elliot (1849-1919) was a theosophist who elaborated Helena Blavatsky's concept of root races in several publications, most notably The Story of Atlantis (1896) and The Lost Lemuria (1904), later combined in 1925 into a single volume called The Story of Atlantis and the Lost Lemuria. In 1893 he married Matilda (Maude) Louise Travers (1859-1929). W. Scott-Elliot came into contact with theosophist Charles Webster Leadbeater who said he received knowledge about ancient Atlantis and Lemuria from the Theosophical Masters by astral clairvoyance. Leadbeater transmitted his clairvoyant findings to Scott-Elliot, who undertook scholarly research to back them up.
