Kellogg's is a premier brand name associated with breakfast cereals. Dr John Harvey and Will Kellogg were both pioneers in health reform at a time when industrial urbanisation resulted in poor health outcomes for swathes of Western people. John Harvey was a doctor who believed in natural remedies, natural food and exercise. He also invented simple precursor exercise devices that are now seen in gymnasia up and down the country. The story was made famous in the film 'The Road to Welville' While not all of his beliefs and remedies are supported by modern science, a significant proportion of his understandings are now beyond dispute.
