That’s the greatest thing since sliced bread — how often have you heard that? Sounds like sliced bread is the gold standard — you have to be as good as that.

So who thought of selling bread already sliced? It’s a relatively new idea. We celebrate its 90th anniversary this year.

An inventor named Otto Rohwedder, of Davenport, Iowa, developed a bread slicer, thinking American housewives would welcome it as a time saver.

But it took a while for bakers to warm to the idea. Sliced bread, after all, would become stale faster than a whole loaf — right?

Otto’s machine sliced bread and wrapped it tight, keeping it fresh.

The Chillicothe Baking Company, of Chillicothe, Missouri, was willing to give Rohwedder’s invention a chance. It began selling sliced bread on July 7, 1928 and became an immediate success.

It was especially successful for Wonder Bread, which was distributing sliced bread around the country in just two years.

An executive for the Taggart Baking Company, Elmer Cline, was watching a balloon race at the Indianapolis Motor Speedway when he said to a friend how wonderful balloons were.

The light bulb went off — he called his new bread Wonder Bread and the dots on the package are supposed to be red, yellow and blue balloons.
