John Kellogg
John Harvey Kellogg was an American physician born in Michigan in 1852. He founded a sanitarium focusing on nutrition, vegetarianism, and exercise, and with his brother, he invented the common breakfast cereal cornflakes. Kellogg helped establish the American Medical Missionary College and was an early advocate for pasteurizing milk before drinking it. Besides The Hygienic Cook Book, Kellogg authored several other books, including Plain Facts for Old and Young, New Dietetics, and Ladies' Guide in Health and Disease. He died of pneumonia in 1942.
