John Harvey Kellogg, known for his line of prepared breakfast cereals, was issued a patent for a "Process of Producing Alimentary Products" in 1898,[REF][REF] and used peanuts, although he boiled the peanuts rather than roasting them.
Early peanut-butter-making machines were developed by Joseph Lambert, who had worked at John Harvey Kellogg's Battle Creek Sanitarium, and Dr. Ambrose Straub who obtained a patent for a peanut-butter-making machine in 1903 [REF].
