Erich von Däniken
His was the very first DISCLOSURE book I read before it was called that - (in Upper Darby HS library)<---I guess I should be glad they carried this one....no Sitchin in public libraries back then. Erich von Däniken's book, "Chariots of the Gods" - in 1968 - I didn't read it until 1975....but - it all made sense - again - I remember distinctly how this guy would be hammered and ridiculed for his research and his conclusions, and frankly he didn't come up with many, he really just wanted to present what he believed was the truth. Bless him for that! His main website is here.
