"Kellogg was not only a physician, surgeon, author, and administrator, but also an inventor. Although less discussed in comparison to his food creations, he designed and improved upon a number of medical devices that aided in his surgical operations and in treatment modalities falling under the term "physiotherapy" that were regularly used at the Battle Creek Sanitarium. Dr. Kellogg attempted to popularize these treatment methods, including electrotherapy, hydrotherapy, and motor therapy, in his work The Home Handbook of Domestic Hygiene and Rational Medicine first published in 1881.^[25]

"As he specialized in certain gynecological surgeries (particularly hemorrhoidectomies and ovariotomies) and gastrointestinal surgeries, he developed various instruments for these operations including specialized hooks and retractors, a heated operating table, and an aseptic drainage tube used in abdominal surgery.^[26] Additionally, Kellogg took keen interest in devising instruments for light therapy, mechanical exercising, proper breathing, and pure water. His medical inventions spanned a wide range of applications and included a hot air bath, vibrating chair, oscillomanipulator, window tent for fresh air, pneumograph to graphically represent respiratory habits,^[26]loofah mitt, and apparatus for home sterilization of milk.^[26] Some of his inventions were even considered fashionable enough to be found in the first class gymnasium of the Titanic^{[27]" (Wikipedia article on John Harvey Kellogg, accessed 03-2017).}

"John Harvey Kellogg is best known for the invention of the famous breakfast cereal, Corn Flakes, in 1878. Originally, he called this cereal Granula, which he later changed to Granola in 1881. However, due to patent rights, he had to once again change the name to Corn Flakes.^[19]

"These Corn Flakes were invented as part of his health regimen to prevent masturbation. His belief was that bland foods, such as these, would decrease or prevent excitement and arousal.^[20] Kellogg was inducted into the National Inventors Hall of Fame in 2006.

"John Kellogg and his brother Will Keith Kellogg started the Sanitas Food Company to produce their whole grain cereals around 1897, a time when the standard breakfast for the wealthy was eggs and meat, while the poor ate porridge, farina, gruel, and other boiled grains.^[ John and Will later argued over the recipe for the cereals (Will wanted to add sugar to the flakes). So, in 1906, Will started his own company, the Battle Creek Toasted Corn Flake Company, which eventually became the Kellogg Company, triggering a decades-long feud. John then formed the Battle Creek Food Company to develop and market soy products.

"A patient of John's, C. W. Post, would eventually start his own dry cereal company, Post Cereals, selling a rival brand of corn flakes. Dr. Kellogg later would claim that Charles Post stole the formula for corn flakes from his safe in the Sanitarium office" (Wikipedia article on John Harvey Kellogg, accessed 03-2017).

"Purveyors of spiritualized medicine have been legion in American religious history, but few have achieved the superstar status of Dr. John Harvey Kellogg and his Battle Creek Sanitarium. In its heyday, the 'San' was a combination spa and Mayo Clinic. Founded in 1866 under the auspices of the Seventh-day Adventist Church and presided over by the charismatic Dr. Kellogg, it catered to many well-heeled health seekers including Henry Ford, John D. Rockefeller, and Presidents Taft and Harding. It also supported a hospital, research facilities, a medical school, a nursing school, several health food companies, and a publishing house dedicated to producing materials on health and wellness. Rather than focusing on Kellogg as the eccentric creator of corn flakes or a megalomaniacal quack, Brian C. Wilson takes his role as a physician and a theological innovator seriously and places his religion of 'Biologic Living' in an on-going tradition of sacred health and wellness. With the fascinating and unlikely story of the 'San' as a backdrop, Wilson traces the development of this theology of physiology from its roots in antebellum health reform and Seventh-day Adventism to its ultimate accommodation of genetics and eugenics in the Progressive Era" (publisher).
