The company also produces several pet food brands, including Rachael Ray Nutrish, Kibbles 'n Bits, and 9Lives, and markets Peter Pan Peanut Butter.

C. W. Post established his company in Battle Creek, Michigan, having lived there since 1891, when he was a patient at a holistic sanitarium operated by Dr. John Harvey Kellogg.

As of January 2013, Eliza's Quest Food had succeeded in returning Postum to many grocery stores across the United States and Canada.

In 1897, Post introduced his first dry cereal, a crunchy blend of wheat and barley, which he called Grape Nuts.

Post underwent an apparently successful appendectomy at the Mayo Clinic, but shortly after returning home to recuperate, he died of a self-inflicted gunshot wound.

The 1920s was a period in which common stock was still considered highly speculative, and consequently the newly issued shares carried a dividend at the rate of $5.00 per year.

Starting in 1925, under the leadership of financier (and at one point, son in-law to the founder), E. F. Hutton as chairman and Colby M. Chester as president, Postum Cereal made the first of a series of corporate acquisitions which would within a few years transform it into the dominant U.S. packaged grocery products manufacturer.

However, Wait was unsuccessful in marketing Jell-O, and in 1899, he sold the rights to it for $450 to a neighbor, Orator Francis Woodward, who had founded the Genesee Pure Food Company in 1897.

Genesee became the Jell-O Company in 1923, the same year it began marketing D-Zerta, a sugar-free gelatin, and a powdered mixture for making ice cream in the kitchen.

In 1926, Postum Cereal acquired Igleheart Brothers, Inc (established in 1856), the makers of Swans Down cake flour, and followed this with the purchase of the Minute Tapioca Company.

The acquisition spree continued in 1927 with the purchase of two similarly named confectionery companies, chocolate-maker Walter Baker (founded in 1765, making it the oldest component of the Postum constituent companies), and coconut-processor Franklin Baker, which had begun early in the 19th century as a flour broker, but whose confectionery products dated from 1895.

And late in the year, Postum Cereal began selling its first coffee product, "Sanka", by obtaining US marketing rights from Dr Ludwig Roselius of Bremen, Germany.

Financially, the year culminated on October 1 with the inclusion of Postum, Inc in the newly reformulated Dow Jones Industrial Average of 30 common stocks.

In 1924, with backing from three investors, he formed the General Seafoods Company, in Gloucester, Massachusetts, to produce frozen haddock fillets packed in plain cardboard boxes.

In 1926, she had put into port at Gloucester on her yacht, Hussar (IV), and was served a luncheon meal which, she learned to her amazement, had been frozen six months before.

Although she eventually became the richest woman in America because of her business genius, it took Marjorie Post three years to finally convince Postum's management to acquire the company.

Housewives quickly realized that keeping packages of frozen food in the icebox could mean fresher meals and fewer trips to the market.

In February 2023, Post Holdings announced its acquisition of pet food brands like 9Lives, Kibbles 'n Bits and Gravy Train.
