Charles Fort (1874–1932)

American writer; compiled reports of anomalous phenomena; author of The Book of the Damned (1919); intellectual grandfather of the ancient aliens tradition; introduced the framework of anomalous data + mainstream dismissal = hidden truth; speculated about Earth as a "farm" managed by alien beings.

Russian mystic; co-founder of Theosophy; author of Isis Unveiled (1877) and The Secret Doctrine (1888); proposed that human civilization descended from ancient advanced peoples guided by cosmic intelligences; established the cultural template of ancient advanced civilizations with non-human guidance that subsequent ancient alien theorists drew upon.

Louis Pauwels (1920–1997) and Jacques Bergier (1912–1978)

French authors; Le Matin des Magiciens / The Morning of the Magicians (1960); established the "fantastic realism" framework that set the cultural context for von Daniken's global success eight years later.
