To continue with posts about St. Louis history as reported by KSDK, here’s a bit about Kraft and the birth of Macaroni and Cheese.

In 1937, poor sales leads the National Dairy Products company to adopted the idea of one of its St. Louis salesmen. The idea? To combine grated American cheese with Tenderoni Macaroni, thus Kraft Macaroni and Cheese was born.

So next time you get those “blue box blues” you have the great city of St. Louis to thank.
