John Harvey Kellogg (1852–1943), a Seventh-day Adventist physician, directed Michigan's Battle Creek Sanitarium and invented Corn Flakes in the 1890s as bland food to suppress libido and combat masturbation, which he deemed a cause of illness and insanity. He advocated celibacy, minimal procreation, and harsh treatments like acid on genitals, detailed in his book "Plain Facts for Old and Young"; his brother Will later commercialized sweetened Corn Flakes in 1906, launching the global brand.
