20 November 1952 (claimed); book 1953 / T062
George Adamski’s claimed meeting with a Venusian
Desert near Desert Center, California

Witness account
Adamski said he met a human-looking visitor from Venus during a desert excursion. His account described communication about humanity and destructive weapons, and became a central text of the contactee movement through the 1953 book coauthored with Desmond Leslie. Later books expanded the story into journeys and meetings with other space visitors.
Public record
Books, photographs, alleged footprint evidence and the supporting group’s statements document the claims. The encounter’s cosmic setting and benevolent message also fit Adamski’s broader spiritual teaching, examined by historians of UFO religion.
