At the American Business History Center, we are always looking for ways to connect the present to the past. And hopefully learn some lessons along the way.
May is a critical month in the world of sports. The first Saturday in May (May 2) will bring the 152nd running of the Kentucky Derby. On May 24, the 110th Indianapolis 500 comes along…. historically the most attended single-day event in sports. In 2016, the 100th running brought out about 500,000 people. The bleachers and grandstands alone seat about 250,000! Both races are great American traditions.
But how many know their connection to an everyday kitchen product, baking powder?
During and immediately after the Civil War, New Englander Eben Horsford’s Rumford Baking Powder pioneered the industry, making it easier to bake bread.
In 1873, another company, the Royal Baking Powder Company, was set up in Manhattan. Royal began to advertise heavily and create recipes and cookbooks. Under the Hoagland brothers, Royal’s sales rose from $350,000 in 1876 to $3 million in 1888, at which time the company was spending the huge sum of $300,000 per year on advertising. By 1917, the Royal Company had $30 million in assets, bigger than Coca-Cola, H.J. Heinz, or Campbell Soup. The company was phenomenally profitable and led the industry, which drew many competitors.
With his new, “better,” formula, William Wright entered the fray with his Calumet Baking Powder in 1889. With colorful packaging and even more aggressive advertising, Calumet passed Royal in sales by the early 1920s, and in profits in 1927.
The 1920s were an era of corporate mergers and acquisitions. With support from big New York banking houses including J.P. Morgan and E.F. Hutton, two “food conglomerates” were created: General Foods (from the Postum cereal empire) and Standard Brands (formed around Fleischmann’s yeast). In 1928, Wright sold Calumet to Postum, soon renamed General Foods, America’s largest food company after the big meatpackers like Swift and Armour and National Dairy Products (later renamed Kraft). In 1929, Standard Brands bought Royal. The competition was now turned over to deep-pocketed giants. The owners who sold out were rich.
Calumet’s William Wright had bought a Kentucky horse farm in 1924 and renamed it Calumet Farm. When he died in 1931, he left $55 million to his son Warren, who threw his full energies into thoroughbred racing. Between 1941 and 1991, Calumet-bred horses won a record nine Kentucky Derbies, including Triple Crown winners Whirlaway and Citation. Calumet Farm was later sold and went into decline but is on the comeback and remains one of the most famous names in racing.
Meanwhile, giants General Foods and Standard Brands ran big ad campaigns for Calumet and Royal baking powders. They thought they “owned the market.” But there was a thorn in their side.
For years, Terre Haute, Indiana’s regional wholesale grocery firm Hulman & Company had marketed Clabber Girl baking powder in Indiana and neighboring states. By the 1930s, the founder’s grandson, Anton “Tony” Hulman, Jr., was out of college and helping run the business. Tony thought Clabber Girl had no future as a regional product…. he needed to “go national.” While the New York behemoths General Foods and Standard Brands were distracted by their big product assortments, Tony focused on baking powder. Over time, he won. Today, Clabber Girl has about two-thirds of the U.S. market, and now also owns the Royal brand in America.
But Tony Hulman, like his father, also loved speed and racing. In 1945, he bought the Indianapolis Motor Speedway for $750,000. The historic but dilapidated facility had not been used during the War. His advisors told him not to buy it, or, if he did, to tear it down and put the huge tract of land to better use. Tony didn’t listen.
The Hulman family continued to own both the baking powder company and the IndyCar track and series at the time we first published this article in 2019.
Later in 2019, they sold the food business to B&G Foods, owners of such brands as Crisco, Green Giant, Cream of Wheat, and Durkee, for $80 million.
Also, that year, automotive and auto racing entrepreneur Roger Penske and his private Penske Entertainment Company bought the IndyCar series and the Indianapolis Motor Speedway for $250-300 million. They later sold a one-third interest to Fox Corporation. Since Penske took over, comparing 2025 with pre-Covid 2018, attendance at the 500 is up 17%, TV viewership is up 44%. Many of the road, street, and oval races in the series have set new records for attendance and TV viewership.
Publicly owned Churchill Downs Inc. owns the track and holds the Kentucky Derby.
We suggest you watch both exciting and very competitive events.
Who would’ve guessed that those little cans of baking powder would propel so many cars and horses to record speeds? History is made in strange ways!
