CIA informant claimed Hitler survived WWII, living as Adolph Schuttlemeyer.
This came from recently declassified CIA documents.
Y'know, "Heil, Schuttlemayer!" doesn't really have a snappy ring to it.
The argument that Hitler survived the bunker and that it wasn't his body in the bunker goes back a long way. I don't know when it was first seriously debated, but I think it was in his second book when the famous Los Angeles coroner Thomas Noguchi wrote a chapter on it back in about 1987. Then there were a couple books on the theory a few years ago, one that argued that he went to Argentina and the other to, I believe, Italy. I think the more credible of the two books was named "Rat Line" by Peter Levenda.
