For ages, Chillicothe, a town of 9, 500 along the route, felt left out. As far as anyone knew, nothing had been invented there of equal stature.

Then, in 2001, a local journalist, combing through microfilm of old newspapers, stumbled upon a slice of American innovation long overlooked by local residents and state historians. The headline on an old news clipping said: “SLICED BREAD IS MADE HERE.”

It appeared on the front page of the Chillicothe Constitution-Tribune on July 6, 1928, the day before the first machine-sliced bread would be sold to customers. “The Chillicothe Baking Company,” it said, “has installed a power driven multi-bladed bread slicer which performs a feat which heretofore had been considered by bakers as being impossible — namely, the slicing of loaves.”

That bakery, run by Marion “Frank” Bench, was the first in the nation to sell commercially sliced and wrapped bread. Other bakers said it couldn’t be done without the loaves losing their freshness. The bread was first sold the same year that Disney created Mickey Mouse, just months before the Great Depression.

A Chillicothe newspaper ad promoted the breakthrough as “the greatest forward step in the baking industry since bread was wrapped.” Soon others were using the phrase “the greatest thing since sliced bread” to hype inventions that followed and, for that matter, a lot of other things. President Barack Obama invoked the saying after the Chicago Cubs won the World Series in 2016, their first title in 108 years.

“No one says, ‘It’s the greatest thing since the cellphone,’” said Ed Douglas, president of Chillicothe’s Slice Bread Corporation, because the automated bread slicer is “the American innovation by which others are measured.”

Now Chillicothe is hoping for additional recognition. A bill passed by the Missouri House on Wednesday calls for designating July 7 as “Missouri Sliced Bread Day.” The measure was sent to state Senate for consideration. The St. Louis Post-Dispatch’s editorial board called it the legislature’s “weirdest bill.”

“It’s a wonderful bill. Sliced bread is major deal,” countered a co-sponsor of the bill, Rep. Nate Walker (R) of Kirksville, who last month proposed changing part of U.S. Route 63 in northeast Missouri to “Bluegrass Queen Rhonda Vincent Highway.”

The bread bill celebrates Chillicothe’s role in food history. But it doesn’t mention that an Iowan, Otto Frederick Rohwedder, created the bread-slicing machine used in Bench’s bakery. Although the invention forever changed the way Americans eat, it did not make Rohwedder famous or wealthy.

Rohwedder didn’t set out to become an inventor. He earned a degree in optics in 1900 from the Northern Illinois College of Ophthalmology and Otology in Chicago. Then he moved to Missouri, where he eventually operated three jewelry stores in St. Joseph, about 70 miles west of Chillicothe.

On the side, he tinkered with a design for a mechanized bread slicer. In 1916, he sold his jewelry business and moved back to his home town of Davenport, Iowa, to focus his energy on the slicer and recuperate from an illness.

Rohwedder wasn’t the first to attempt making an automated bread slicer, according to the Atlantic: “While the earlier bread-cutting devices using parallel blades appear in America in the 1860s, they sat on the shelf for decades, awaiting the introduction of other machines capable of producing loaves of uniform shape, size and consistency.”

In 1917, Rohwedder’s prototype, including the blueprints, were destroyed in a fire at an Illinois factory that he hoped would produce his commercial bread slicers. It would take nearly a decade for him to secure the funds needed to begin manufacturing again.

“It was a real story of determination,” Douglas said.

As he improved his invention, Rohwedder sought feedback from homemakers to determine how thick to cut the slices (half an inch). He also had to find a way to ensure the bread would stay fresh once it was sliced. First, he inserted large U-shaped pins at both ends of the bread to keep the pieces from separating. Then he created a process so that the bread was quickly sealed in a bag after being sliced.

Many bakers initially opposed factory-sliced bread. But Rohwedder’s baker friend in Chillicothe signed on. After a few years in business, Frank Bench had fallen on hard times and seemingly had nothing to lose, Douglas said.

The patent for the automated slicer explained how it worked, according to the Smithsonian: “The machine moved the bread into the slicer and then a series of ‘endless cutting bands’ sliced the loaf before moving it along to where it could easily be packaged by a specially designed bread wrapping machine — another patent of Rohwedder’s.”

The 1928 ad in the Chillicothe newspaper announcing the sliced bread offered instructions: “open wrapper at one end” and then “pull out pin” holding the slices together. The product was a hit. Customers appreciated the convenience and ability to make uniform sandwiches.

“Sliced bread was here to stay and the baking industry was beating a path to Rohwedder’s door,” the Chillicothe newspaper reported. “Over the next 14 months, Rohwedder took orders for more than 230 bread slicing machines from bakeries through the country.”

Subsequent slicers were vastly improved. By 1930, the Continental Baking Company introduced the world to sliced Wonder Bread. By 1933, the uniform-sized bread also created a demand for pop-up toasters, which had struggled to find a market until Rohwedder’s invention.

The government banned the sale of pre-sliced bread in 1943 as a wartime measure to conserve resources, such as the packaging materials. But the ban was so unpopular that it was lifted after two months. “Its unpopularity was particularly strong among those housewives who were unable to find a good bread knife to buy,” the Associated Press reported. “Bakeries also urged its revocation.”

Although Rohwedder saw his vision realized, he was forced to sell his patent rights in 1933 during the Great Depression, reportedly to the Micro-Westco Co. of Bettendorf, Iowa, where he became vice president and sales manager of the Rohwedder Bakery Machine Division. He died in Michigan in 1960 at age 80.

In Chillicothe, Bench ran his bakery a few more years before going into another line of work.

After Chillicothe rediscovered its sliced bread history, it learned that Battle Creek, Mich., was also claiming to be the first site where the commercial sliced bread was sold. But Chillicothe had the documentation. In 2003, Richard Rohwedder, the son of the inventor, visited Chillicothe and confirmed that it was the first site. The only other time he had been in town was July 7, 1928, when, “at the age of 13, he held the first loaf of bread to go through his father’s slicing machine,” the Chillicothe Constitution-Tribune reported.

Chillicothe had other records to prove its claim. “We had newspaper articles — a record of history,” said Catherine Stortz Ripley, the Constitution-Tribune’s editor and the journalist who rediscovered the town’s bread history. Additional documentation was found in Otto Rohwedder’s scrapbook, which his son shared during his visit.

“It had an order list of what bakeries wanted the bread slicing machine — probably over 100,” Ripley said. “It showed Chillicothe was the first one. He had notations of when the machines would be delivered.”

The National Museum of American History also says Chillicothe was where the “first commercial bread slicing was used.” Although the initial machine didn’t survive, Rohwedder’s second machine was donated to the Smithsonian by his relatives and is on loan to the Grand River Historical Society Museum in Chillicothe.

In 2003, the town adopted “Home of Sliced Bread” as its official slogan. It hosts events such as the “Sliced Jam Bluegrass Festival” and, of course, bread baking contests. Plans are in the works to turn the bakery’s original building on the corner of First and Elm streets into a visitors center highlighting the town’s claim to fame.

The national attention that sliced bread has brought the town — including appearing as a clue on “Jeopardy!” — has been helpful to the struggling rural economy because of the tourism it brings. Now, residents are hoping the legislature will also give them a boost by adopting a Missouri Sliced Bread Day.

“We’re a viable part of the country as well,” said state Rep. Rusty Black (R) of Chillicothe, who proposed the bill. “Instead of making fun of a small town, they’re looking at Chillicothe as something where innovation is based.”

In other words, a place of “genius.”

Susan Hogan grew up along Missouri Route 36 in Macon, a place so skeptical of Andrew Taylor Still’s style of medicine that he left town and moved 30 miles north to Kirksville, where he founded the nation’s first osteopathic medical school.
