Realized the guy is a recent-ish phenomenon, did a little wikipedia’ing:
"He has a PhD in “Interdisciplinary Studies” from Union Institute & University, a private college that gives degrees by correspondence from Cincinnati, Ohio. According to Null, his thesis was titled, “A Study of Psychological and Physiological Effects of Caffeine on Human Health.”
Union Institute & University is accredited by the North Central Association of Colleges and Schools, but its accreditation does not cover awarding of PhDs in the sciences, only in the humanities. Null is a New York State Registered Dietitian and Nutritionist."
“Gary Null is also a promoter of AIDS denialism, the belief that HIV is harmless or does not exist, and is not the cause of AIDS. Null sells self-produced films on his website that promote AIDS denialism.”
Goes on and on pretty much with your normal anti-vaccination etc etc.
Guy a crackpot or a genius?
