George Adamski (April 17, 1891—April 23, 1965) was a Polish American citizen who became widely known in ufology circles, and to some degree in popular culture, after he claimed to have photographed spaceships from other planets, met with friendly Nordic alien Space Brothers, and to have taken flights with them to the Moon and other planets. He was the first, and most famous, of the so-called contactees of the 1950s.
