How a loaf became a stack of even slices
When Betty White was born in 1922, bakeries still sold most loaves whole. The change came in 1928, when a machine designed by inventor Otto Frederick Rohwedder made it practical for a bakery to cut an entire loaf into uniform slices at once. Its first commercial use was at a bakery in Chillicothe, Missouri—not the sudden arrival of slicers in every grocery store.
The machine had to do more than cut bread. A loaf is soft, springy, and easy to crush, so the blades needed to pass through it cleanly without turning the bread into crumbs or flattening it. Rohwedder’s design used a row of blades to make many parallel cuts in a single operation, producing slices that were more consistent than hand-cut ones.
The packaging problem behind the convenience
Slicing created a new challenge: cut bread dries out faster because more of its soft interior is exposed to air. A neatly sliced loaf was useful only if it could stay fresh long enough to reach the customer and be eaten at home. Bakers therefore had to pair the new machine with packaging that held the slices together and helped protect them from drying.
That combination changed a small kitchen task into a bakery service. People could take a slice without steadying a loaf and sawing through it themselves; sandwiches and toast became easier to prepare, too. The machine did not make bread itself new, but it standardized the final step between bakery and table.
For White’s first six years, a loaf generally arrived intact. The ordinary, ready-to-lift slice familiar to later generations was still a recent innovation when it began appearing in shops.
