We know John Harvey Kellogg as the founder of the Kellogg’s cereal company and the inventor of corn flakes. However, around the turn of the 20th century, Kellogg became renowned for his work as an anti-masturbation crusader, prescribing unusual — and borderline sadistic — solutions to the menace of young boys and girls touching their privates.

The Wikipedia entry is also quite thorough. He was a Seventh-Day Adventist, one of those vegetarian teetotalling non-caffeine-using Saturday-worshipping heretical* evangelicals. (*See the wiki on the SDA church for info. on their heretical beliefs. Interestingly, they came out of the Millerite movement, originally, who had predicted the world would end in 1844.)
He was one of those vegetarian freaks who thought they knew better than everyone else, how everyone should live. And so because of him, instead of good old bacon and eggs, millions eat carb-laden, zero-protein corn flakes for breakfast instead; and millions have pointlessly circumcized their male children, for non-religious reasons. May everything he stood for, one day be utterly repudiated as pure nonsense by everyone.
