Eduard Albert Meier (born 3 February 1937), 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 the seventh reincarnation after six prophets common to Judaism, Christianity, and Islam: Enoch, Elijah, Isaiah, Jeremiah, Immanuel (Jesus), and Muhammad.

[3] 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.

All contacts ceased in 1964, he said, then resumed on January 28, 1975, when he met "Semjase",[11] the granddaughter of Sfath, and shortly thereafter another Plejaren man called "Ptaah".

Meier founded a non-profit organization based on his alleged contacts with Semjase, called the "Freie Interessengemeinschaft für Grenz- und Geisteswissenschaften und Ufologiestudien" (Free Community of Interests for the Border and Spiritual Sciences and Ufological Studies) in the late 1970s and established his "Semjase Silver Star Center".

Some of Meier's photos are claimed by him to show prehistoric Earth scenes, extraterrestrials, and celestial objects from an alleged non-Earthly vantage point.
