Kellogg, W(illie) K(eith) (1860–1951)

US cereal manufacturer and philanthropist. After a first success with a flaked wheat, he, with his brother John, developed a corn flake breakfast cereal. In 1905 he formed the Battle Creek Toasted Corn Flake Company. It was soon renamed the W K Kellogg Company. He achieved great financial success with his line of breakfast foods and revolutionized the world's breakfast-eating habits. In 1930 he established the W K Kellogg Foundation, which became one of the USA's richest philanthropic organizations.

He was born in Battle Creek, Michigan. After working as a broom salesman, he worked with his brother, John Kellogg, during the 1890s to develop new ways to prepare grain for breakfast cereals. He had to fight a long legal battle with his brother over the right to use the family name on his products. He was a pioneer in large national advertising campaigns to promote a product.
