Science in the Kitchen, by Ella Eaton Kellogg, Battle Creek, Michigan, 1904

The Battle Creek Sanitorium began as a small Seventh-Day Adventist facility serving a vegetarian diet. Under the direction of the charismatic, white-suited John Henry Kellogg, the greatly enlarged, sumptuous “San” became world famous. As a health spa, it attracted such notables as Theodore Roosevelt and J. D. Rockefeller, seeking

good health through the spa’s regimen of daily colon cleansing, grape diets (10 to 14 pounds a day) for high blood pressure, salt rubs and electric baths.

Ella Kellogg was her husband’s invaluable partner in running the sanitorium, inventing many specialized vegetarian foods that were served in its dining room. One of these was granola. An early ad for this cereal exhorted readers to eat it “Morning, Noon and Night.” The Kellogg name became known to households across the country through early advertising campaigns and the wide distribution of their ready-to-eat cereals, such as corn flakes. In a tribute to his wife, J. H. Kellogg said of her:

"Without the help derived from this fertile incubator of ideas, the great food industries of Battle Creek would never have existed. They are all direct or indirect outgrowths of Mrs. Kellogg's experimental kitchen, established in the fall of 1883."
