I've been reading an interesting article about him.
Conspiracy theory;
"he died in his hotel room and within 24 hours all his paperwork was taken away, never to be seen again". This was about the time he was working on what sounds like a particle beam weapon. Maybe given the resources, someone thought it might have worked?
What fascinates me about the man is if he couldn't find a 'willing volunteer'
, he would see if things worked by trying them out on himself.
