Hilton Hotema, born George R. Clements, was a 20th-century American alternative health writer, esoteric author and mystic, who also adopted the names Kenyon Klamonti and Dr. Karl Kridler. Future essay(s) on him and his work are in the works!
He authored numerous books on dietetics, fasting, fruitarianism, breatharianism, vitality, cellular regeneration, longevity, higher consciousness, spirituality, alternative medicine and ancient wisdom. One of the more tough swallows of his works are their de-occulting that human beings can live substantially longer than 100 years of age. His works were published by Health Research Booksand are all mostly quite unknown. Digital copies are hard to find but here's a link to what is to my knowledge, all of them - http://www.mediafire.com/file/p1hc6nu5pmc4o5q/Hilton_Hotema_Books.zip
*Author of course long gone, as I would never share someone else's body of work if they were still relying on it for their income.
