Born on October 26, 1854, in Springfield, Illinois, Charles William Post became a pioneering manufacturer in the prepared-food industry. Before finding success with breakfast products, he worked in agricultural machinery as a salesman, manufacturer, and inventor. His search for relief from recurring health problems eventually brought him to Battle Creek, Michigan, where the grain-centered dietary ideas promoted at Dr. John Harvey Kellogg’s sanitarium helped shape his next business venture.
In 1895, Post founded the Postum Cereal Company and introduced Postum, a grain-based alternative to coffee. He followed it with Grape-Nuts in 1897 and Elijah’s Manna, a cornflake cereal, in 1904; the latter became known as Post Toasties. These products helped establish a highly profitable business, but their success depended on more than what went into the package. Post used extensive advertising, product sampling, and persuasive sales techniques to win over consumers and grocers.
Post’s legacy lies as much in how he sold breakfast as in what he manufactured. His campaigns linked packaged foods with health and well-being, sometimes making extravagant medical claims—including the assertion that Grape-Nuts could cure appendicitis. That claim drew scrutiny and a legal dispute with Collier’s Weekly, exposing the troubling side of his promotional methods. His career connects two enduring features of the packaged-food business: the convenience of ready-to-eat products and the power—and potential excesses—of advertising.
