von Däniken, Erich
(1935-2026) Swiss author of a series of purportedly nonfiction books, beginning with Erinnerungen an die Zukunft (1968; trans Michael Heron as Chariots of the Gods? 1969), which, based on a mass of often suspect and internally inconsistent data, argues that the Earth was visited by at least one Alien spacefaring race before and at the dawn of historical time; thus, for example, the Great Pyramid of ...
