- George's book talks about the history of EVPs, and obtaining audio from ghosts and spirits. One of the things that piqued my interest was his discussion of Thomas Edison. He said that Edison said several times that he may have thought communicating with the dead was possible. At one point, Edison said "There is a doubt. I am not sure. That's the reason I am experimenting. But if I didn't believe, I wouldn't try." Noory said that if Edison tried to work on a prototype, none was found when he died.
Noory's book is filled with many people who tried creating "telephones" to talk with the dead, including an inventor in Scotland who put a telephonic apparatus to the throat of mediums in order to "hear spirit voices" coming from within the medium. That invention came about in the late nineteenth century.
Interesting stuff- and check out George Noory's book "Talking to the Dead" for more info on trying to obtain electronic recordings and EVPs.
