John Harvey Kellogg and in 1898 released the first batch of Sanitas Toasted Corn Flakes. A modified version with a longer shelf life was released in 1902. By that time, both "Granose Biscuits" and "Granose Flakes" were available. Will Kellogg continued to develop and market flaked cereal. When he proposed adding sugar to the flakes, John would not agree to the change. So, in 1906, Will started his own company, the Battle Creek Toasted Corn Flake Company. This marked the start of a decades-long feud between the brothers. Will's Battle Creek Toasted Corn Flake Company would eventually became the Kellogg Company, while John
Joseph Kellogg first commercial flour mill in Oregon. He also built several of the first sawmills. Kellogg's land claim was next to that of Lot Whitcomb, at Milwaukie. Kellogg, Whitcomb and William Torrence laid out the town site of what they hoped would be the principal city in Oregon. In Milwaukie, Kellogg built a sawmill and a schooner. Kellogg, Whitcomb and Torrence loaded the schooner with provisions from the adjoining farms, took it to California, and there sold both vessel and cargo, and with the proceeds they bought the brig "Forest", which they used in the lumber trade between Oregon and California.
