W. K. Kellogg persuaded his brother to serve the food in flake form. Soon the flaked wheat was being packaged to meet hundreds of mail-order requests from guests after they left the Sanitarium. However, Dr. John Harvey forbade his brother Will from distributing cereal beyond his consumers. As a result, the brothers fell out, and W. K. launched the Battle Creek Toasted Corn Flake Company on February 19, 1906. Convincing his brother to relinquish rights to the product, Will's company produced and marketed the hugely successful Kellogg's Toasted Corn Flakes and was renamed the Kellogg Toasted Corn Flake Company in 1909, taking on the current name of the Kellogg Company in 1922.
