John Harvey Kellogg was born on February 26, 1852, in Tyrone, Michigan, into a Seventh-day Adventist family that emphasized health, vegetarianism, and abstinence from stimulants. He became a physician and, in 1876, took over as superintendent of the Battle Creek Sanitarium, a health resort that promoted vegetarian diets, exercise, and hydrotherapy. Patients paid handsomely. Kellogg believed the American diet was a disaster, particularly breakfast: bacon, sausage, fried eggs, biscuits. He wanted something lighter.
In 1894, Kellogg and his brother Will Keith were working on a boiled wheat dough intended to be rolled into thin sheets. One batch was left out overnight and went stale. Rather than discard it, they ran it through the rollers anyway. Instead of forming a sheet, the dough broke into individual flakes. They baked them and served them to patients. The flakes were a hit. Kellogg had accidentally invented a new category of food.

The brothers switched from wheat to corn. Corn flakes were lighter, crisper, and easier to mass-produce. John saw them as health food. Will saw them as a business. The falling out was inevitable. Will wanted to add sugar. John refused. Will left, founded the Kellogg Company in 1906, added sugar, and built a cereal empire. John continued running the sanitarium and publishing books on diet and sexual health, advocating for bland food as a way to curb desire. His views ranged from prescient to deeply problematic.
Kellogg died in 1943 at 91. He never reconciled with his brother. Cornflakes, once a health food designed to suppress appetite, became a sugary breakfast staple marketed to children with cartoon mascots. Every box is a reminder that products escape their creators. Breakfast, like everything else, is negotiable.
