Cold breakfast cereal is a pantry staple in most houses, but who invented it?

**Kellogg’s**

John Harvey Kellogg was a skilled surgeon and health food pioneer. He created a biscuit of oats, wheat, and corn.

Kellogg’s brother, Wil Keith Kellogg, worked with him to come up with breakfast items more wholesome and easier on the bowel than meat. They experimented with boiling wheat and rolling it into sheets, then grinding it. One evening, in 1894, they forgot about a pot of wheat and the next morning, rolled it out anyway. The wheat berries didn’t cohere into a sheet but came out in a mass of flakes. The Kelloggs toasted the flakes... and it was the breakfast history.

W.K. Kellogg was something of a marketing genius. When his brother didn’t want to take risk – fearing it would damage his reputation as a doctor – Will bought him out, and in 1906, packaged wheat flakes for sale.

**Puffed Cereals**

Quaker Oats, the oldest hot cereal company, having been founded on the success of oatmeal, acquired puffed-rice technology in the early 20th century. Cheerios (puffed oats), Sugar Smacks (sugary puffed corn), Rice Krispies, and Trix wandered far from the healthful aims of America’s early breakfast cereal brands.
