While experimenting with shredded wheat cereal, Kellogg and his brother, W. K. Kellogg, accidentally discovered the process for creating flaked cereal. W. K. formed the Battle Creek Toasted Corn Flake Company in 1906. Kellogg was also convinced by his younger brother Will to market his new breakfast foods in what became the wildly successful Kellogg Company, still one of the largest employers in Battle Creek.
