Corn flakes, or cornflakes, are a breakfast cereal made from toasting flakes of corn (maize). The cereal, originally made with wheat, was created by William Kellogg in 1894 for his brother John Kellogg. John Kellogg wanted a food that would be healthy for the patients of the Battle Creek Sanitarium in Michigan where he was superintendent. The breakfast cereal proved popular among the patients, but Will Kellogg wanted to add sugar to increase the popularity. John Kellogg did not approve of this, so Will Kellogg started his own company Kellogg Company to produce corn flakes for the wider public. A patent for the process was granted in 1896, after a legal battle between the two brothers.
