W. K. Kellogg
At the age of fourteen, Will Keith Kellogg (1860 - 1951) began working as a salesman for his father's broom business. Later he worked with his brother Dr. John Harvey Kellogg, at the Battle Creek Sanitarium. In 1894, John, assisted by Will, developed a successful cereal flake. It was first served to patients at the sanitarium and later sold by the Sanitas Food Company. In 1906, W. K. Kellogg launched his own food company to sell Toasted Corn Flakes cereal. The company grew to be the largest manufacturer of ready-to-eat cereals in the world. Kellogg's early personal philanthropies included assistance to rural teachers, to British children orphaned by war, to the blind and to a number of hospitals and medical programs. In 1930 the W. K. Kellogg Foundation was established to promote the health and well-being of children. Today, it is among the world's largest philanthropic organizations.
