George Adamski (17 April 1891 – 23 April 1965) was a Polish American citizen and author 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.
Adamski called himself a "philosopher, teacher, student and saucer researcher", although most investigators concluded his claims were an elaborate hoax, and that Adamski himself was a con artist.Adamski authored three books describing his meetings with Nordic aliens and his travels with them aboard their spaceships: Flying Saucers Have Landed (co-written with Desmond Leslie) in 1953, Inside the Space Ships in 1955, and Flying Saucers Farewell in 1961.
The first two books were both bestsellers; by 1960 they had sold a combined 200,000 copies.
