Sliced Bread Became Shorthand for Human Ingenuity. Fifteen Years After It Debuted, America Outlawed It.
When something dazzles us, we reach for an old phrase: the greatest thing since sliced bread. A smartphone, a scientific breakthrough, a clever gadget — anything we want to crown as a landmark of human invention gets measured against a loaf of pre-cut bread. It is a strange yardstick. Why bread? And why, of all things, bread that someone has already sliced?
Here is the stranger part. That sliced loaf first went on sale exactly 98 years ago today, on July 7, 1928. Bread is one of humanity's oldest foods, but bread cut by machine is younger than a century — younger, in fact, than some people alive right now. And within fifteen years of its debut, the United States made it illegal to sell.
The jeweler who built the machine
The story begins with Otto Frederick Rohwedder, an Iowa-born jeweler who had no stake in baking. He ran three jewelry shops in St. Joseph, Missouri, and might have stayed there — except he grew obsessed with a nuisance most people simply endured: cutting bread by hand. The slices came out uneven, and the work was a chore. Rohwedder pictured a machine that would carve a loaf into uniform pieces, and he bet everything on it, selling his shops to raise the money.
The first blow landed in 1917, when a factory fire consumed his prototype and blueprints. Rebuilding took another decade. Along the way he learned something that would matter later: a cut loaf goes stale faster, because moisture escapes from every exposed face. At first he skewered each loaf with pins to keep the slices from scattering, but the pins slipped out and the pinned loaves looked a mess. So his machine did not merely slice — it wrapped each loaf in waxed paper to hold in freshness, and he soon abandoned the pins. That wrapping would become the hinge of everything that followed.
In 1928, Rohwedder talked an old friend into trying the machine: Frank Bench, a struggling baker in Chillicothe, Missouri. The two placed an ad in the local Constitution-Tribune under the headline "Sliced Bread Is Made Here," promising "the greatest forward step in the baking industry since bread was wrapped." On July 7, 1928, loaves of Kleen Maid sliced bread appeared on Bench's shelves.
The response was immediate. Bench's sales leapt 2,000 percent in two weeks. No one had to saw a loaf into pieces for every meal anymore. Wonder Bread rolled out sliced loaves nationwide in 1930; by 1933, sliced bread outsold the unsliced kind. The pop-up toaster took off in its wake — uniform slices finally gave the machine something to toast.
This is where "the greatest thing since sliced bread" comes from — more or less. People often trace the idiom straight to that Chillicothe ad, but no one actually knows who first said "since sliced bread," or when. What is certain is that by the 1940s the phrase had hardened into the ultimate compliment for anything new.
the year the U.S. banned its sale
The day the government banned bread
On January 18, 1943, Claude R. Wickard — the U.S. secretary of agriculture — issued Food Distribution Order No. 1. Its central provision was blunt: bakeries could no longer sell bread already sliced. If you wanted slices, you would cut them yourself.
The man who signed the order had made history two months earlier, too. This was the same Wickard of Wickard v. Filburn (1942), the Supreme Court case that held Washington could regulate even the wheat an Ohio farmer grew to feed his own livestock. A farmer's handful of grain, a bakery's bread knife — in each, the federal hand reached into the smallest domestic choices.
The country was two years into the Second World War. Sugar, gasoline, tires, and coffee had been rationed since 1942, and Americans had learned to bear it. Bread was another matter. Time magazine, on February 1, 1943, described housewives wrestling with their grandmothers' serrated knives, turning out lopsided slices the toaster refused, then bolting for the corner bakery to buy rolls.
Why bread, of all things? The official reason was paper. It was Rohwedder's old problem again: sliced bread stales faster, so it needs heavier waxed wrapping to stay fresh — and wax was a war material, used to shield vehicles and equipment from the weather. To that, officials added the aim of holding down flour prices, plus the steel in slicing machines and the wheat supposedly wasted when families tossed out stale slices.
Here is the quiet machinery beneath the story. Slicing a loaf was never merely a convenience that spared you a knife. The instant a loaf was cut, it acquired something it had never needed before: packaging. An unsliced loaf can sit a day and only its crust hardens; a sliced loaf dries across every open face. So it had to be wrapped more, and more heavily. In peacetime that cost stayed invisible. Under wartime scarcity, it surfaced.
A ban that lasted under two months
The trouble was that the justifications kept crumbling. A wheat shortage? That year's harvest had left the country sitting on more than a billion bushels — a two-year supply even if not one new grain were harvested. Waxed paper? Bakeries had months of it in hand. Steel for machines? Most bakeries already owned their slicers and were not buying new ones.
Then came the fairness problem. Within a week, the mayor of New York announced that bakeries already fitted with slicing machines could keep using them — splitting the city, overnight, into the sliced and the unsliced. The whole point of the ban dissolved. The backlash spread to politicians and newspapers.
On March 8, 1943, Wickard rescinded the order. It had stood for under two months. Rather than admit its unpopularity, he said only that the savings had come to less than expected and that bakers had a four-month supply of waxed paper after all — grasping for a rationale even as he let one go. Sliced loaves returned to the shelves, and by the 1950s Americans were eating six slices of factory bread a day. The two-month uproar shrank into a wartime curiosity. And the bread went on being the measure of every new thing under the sun.
Ordinariness arrives after resistance
What this story leaves behind is not a punchline about a government that banned bread. The sharper point sits earlier. The very benchmark we grab for when we call something "the greatest" was, at its own birth, doubted by bakers who feared it would go stale, shrugged off by shoppers who assumed bread was something you cut at home, and finally forbidden by the state.
So the story travels well beyond bread. When some object becomes the yardstick — "the greatest thing since X" — it is worth asking how X itself was received when it was new. Ordinariness usually arrives only after resistance.
Bread was not alone. Coffee, which we now drink everywhere, was nearly outlawed in 1675, when England's Charles II declared coffeehouses dens of seditious gossip and ordered them shut — only to withdraw the proclamation days before it took effect, under a wave of protest. The umbrella, which anyone now opens without a second thought, drew jeers when Jonas Hanway carried one of the first through 1750s London; mocked as effeminate and too French, it took decades to become ordinary.
The thing we doubt today may turn out to be someone's sliced bread.
