The famous Kellogg Cereal

In 1894, the Kellogg brothers worked at a hospital and health spa in Battle Creek, Michigan. In a quest to provide healthy meals to the patients, the brothers came up with several recipes using wheat grains and good-for-you substitutes. One day, mistakenly they left some wheat sitting out. On returning they found that the wheat had become stale. They decided to use it anyway, hoping to make sheets of the dough. Once rolled the grains came out as thin, flattened flakes. They served these roasted flakes and that was the light-bulb moment for them. Will Keith Kellogg, the younger of the two, went on to create his own cereal business which famously sells the Kellogg's® Corn Flakes today.
