Vegetarian American doctor who promoted exercise and purging the body of pathogenic bacteria. He didn’t think masturbation was ‘purging’ the body of excess sperm and fought hard against it. This attitude to the body stemmed from his belief that sexual desires were unhealthy and almost complete sexual abstinence was good for you (Kellogg never had sexual relations with his wife, and all their children were adopted). He’s better-known as the inventor of corn flakes and peanut butter. Kellogg treated a host of celebrities: American president William Taft, explorer Roald Amundsen, industrialist Henry Ford and even the French actress Sarah Bernhardt.
