Eduard Albert Meier, commonly nicknamed "Billy", is the founder of a UFO religion called the "Freie Interessengemeinschaft für Grenz- und Geisteswissenschaften und Ufologiestudien" (Free Community of Interests for the Border and Spiritual Sciences and Ufological Studies) and alleged contactee whose UFO photographs are claimed to show alien spacecraft. Meier claims to be in regular contact with extraterrestrial beings he calls the Plejaren. He also presented other material during the 1970s such as metal samples, sound recordings and film footage. Meier claims to be the seventh reincarnation after six prophets common to Judaism, Christianity, and Islam: Enoch, Elijah, Isaiah, Jeremiah, Immanuel (Jesus), and Muhammad.

Meier has been widely characterized as a fraud by skeptics and ufologists, who suggest that he used models to hoax photos claimed to show alien spacecraft. Meier's prophecies repeatedly blame Jews (whom he refers to as "gypsies") for future atrocities.
