John Harvey Kellogg and Will Keith Kellogg were brothers from a Seventh-day Adventist family in Battle Creek, Michigan. They had little education, because their parents expected Christ’s Second Coming before they would need it, but John Harvey managed to get a medical degree. He was a fanatical advocate of what he called ‘biologic living’, which involved vegetarianism, no alcohol or tobacco, no tea, coffee or condiments and minimal quantities of eggs and dairy products.
That is very interesting...Thanks
