Granula wasn't much like the cereal we eat today. The first manufactured breakfast cereal, it was developed in 1863 by a doctor and health reformer named James Caleb Jackson. Jackson believed, as many did at the time, that sicknesses were based in the digestive system.

Where did cereal came from?

The first cereal grains were domesticated by early primitive humans. About 8,000 years ago, they were domesticated by ancient farming communities in the Fertile Crescent region. Emmer wheat, einkorn wheat, and barley were three of the so-called Neolithic founder crops in the development of agriculture.

When did they invent cereal?

Here are some highlights. In 1863, James Caleb Jackson, a religiously conservative vegetarian who ran a medical sanitarium in western New York, created a breakfast cereal from graham flour dough that was dried and broken into shapes so hard they needed to be soaked in milk overnight. He called it granula.
