George Adamski, Polish-American ufologist and author (born 1891)

George Adamski was a Polish-American author who became widely known in ufology circles, and to some degree in popular culture, after he displayed numerous photographs in the 1940s and 1950s that he said were of alien spacecraft, claimed to have met with friendly Nordic alien or "Space Brothers", and claimed to have taken flights with them to the Moon and other planets.
