‘The Kelloggs,’ by Howard Markel

In 1890, 14 years after Dr. John Kellogg converted a two-story home into a health institute, his Battle Creek Sanitarium had evolved into a massive medical center. The Michigan facility included a five-story hospital; 400 acres of land to grow the food seven to 10,000 patients consumed each year; canning and food manufacturing plants; 20 cottages for wealthy clients; and a charity hospital. With hundreds of publications bearing his name, Kellogg had an international reputation as a surgeon, an authority on nutrition, exercise and natural healing, and a patron saint of “wellness.”

In time, however, John’s younger brother Will would become the Kellogg.
