This guy reminds me of another Chicago quack:

Robert S. Mendelsohn, M.D. (1926-1988) engaged in irresponsible criticism of the medical profession and science-based health care during most of his medical career. Although he had taught at several medical schools and been chairman of the Illinois state licensing board, Mendelsohn considered himself a “medical heretic.” He opposed water fluoridation, immunization, coronary bypass surgery, licensing of nutritionists, and screening examinations to detect breast cancer. One of his books charged that “Modern Medicine’s treatments for disease are seldom effective, and they’re often more dangerous than the diseases they’re designed to treat”; that “around ninety percent of surgery is a waste of time, energy, money and life”; and that most hospitals are so loosely run that “murder is even a clear and present danger…”

We had a poster here a while back named “clear vision” who promoted this lunatic.
I wonder if both “doctors” were connected?
