For more pseudo-science and a few good laughs, look up John Harvey Kellogg, the brother to the cereal mogul. Better yet, look up the comical farce The Road to Wellville with Sir Anthony Hopkins as the good doctor, which goes over the gentleman's notions of "healthy living."
Wasn't John Harvey Kellogg the cereal guy? The wikipedia article on him talks about him inventing corn flakes and the corn flakes article links back to him.
It was the brother Will Keith Kellogg who was more interested in the business side, vs John the health nut, who made it more popular. John went on to make his version of a "sanitarium."
John Harvey Kellogg and Will Keith Kellogg kinda invented it together. John Harvey was a fucking nutcase and did everything he could to reduce sexual desires (by eating a bland vegetarian diet) and promote health (with enemas ).
They competed on store shelves against each other for a while. John Harvey sold his bland version under the Sanitas brand and Will Keith with his sweetened version under the Kellogg brand, as kind of a fuck you to his brother. He was riding on John Harvey's fame, but also prevented John from using the Kellogg's name on his own product.
The cereal sold today is from Will Keith's Kellogg company.
Reverend Sylvester Graham didn't create the graham cracker or graham flour but both were named after him. he was a major figure in the iteration of the vegan movement/lifestyle that existed in the 18th century.
What's funny is, his story has a neat parallel to Doctor James H. Salisbury who is credited similarly with the invention of the Salisbury Steak, AND there was a stint of time during which they were both concurrently alive.
Their dietary policy positions were basically diametrically opposed to one another and i feel it's a great injustice of history that they probably never crossed one another's paths or had a big debate.
I really wish epic rap battles of history would cover this...
