Sliced bread

Sliced bread is a loaf of bread, sliced with a machine and packaged for convenience, as opposed to the consumer cutting it with a knife. It was first sold in 1927, advertised as "the greatest forward step in the baking industry since bread was wrapped". By 1933, around 80% of bread sold in the US was pre-sliced, leading to the popular idiom "greatest thing since sliced bread".

History

Otto Frederick Rohwedder of Davenport, Iowa, United States, invented the first single loaf bread-slicing machine. A prototype he built in 1912 was destroyed in a fire, and it was not until 1928 that Rohwedder had a fully working machine ready. The first commercial use of the machine was by the Chillicothe Baking Company of Chillicothe, Missouri, who sold their first slices on July 7, 1928. Their product, "Kleen Maid Sliced Bread", proved to be a success. Battle Creek, Michigan, has a competing claim as the first city to sell bread sliced by Rohwedder's machine; however, historians have produced no documentation backing up Battle Creek's claim. The bread was advertised as "the greatest forward step in the baking industry since bread was wrapped".

St. Louis baker Gustav Papendick bought Rohwedder's second bread slicer and set out to improve it by devising a way to keep the slices together at least long enough to allow the loaves to be wrapped. After failures trying rubber bands and metal pins, he settled on placing the slices into a cardboard tray. The tray aligned the slices, allowing mechanized wrapping machines to function.

W.E. Long, who promoted the Holsum Bread brand, used by various independent bakers around the country, pioneered and promoted the packaging of sliced bread, beginning in 1928. In 1930, Wonder Bread, first sold in 1925, started marketing sliced bread nationwide.
