There were two Kellogg brothers, Harvey and William.
By 1886, Dr. Harvey Kellogg had become director of a religious health spa in Battle Creek, Michigan.
A crusader for healthy food and total sexual abstinence, he believed eating whole grain cereals would reduce sexual urges.
He and his brother, William, developed a process of rolling whole grains to make them into flakes.
William was the spa’s bookkeeper and a good businessman who believed he could make a good profit from the Corn Flakes cereal the two invented, but only if he added malt and sugar for flavor.
Harvey was horrified at that perversion of a good thing, believing sugar to be an aphrodisiac.
Lawsuits flew, William eventually won control of the Kellogg company, and the two brothers remained estranged for the rest of their lives.
