Image: Bread slicing machine from the 1930's
Otto Frederick Rohwedder of Davenport, Iowa, United States, invented the first loaf-at-a-time 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, which produced their first slices on July 7, 1928. Their product, "Kleen Maid Sliced Bread", proved 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.
How is sliced bread used around the world?
Due to its convenience, sliced bread is popular in many parts of the world, and the usual thickness varies by company and country:
sliced bread is sold as either "Extra Thick", "Thick", "Medium" or "Thin" varying across the 5-20mm range.
In the Republic of Ireland , the most popular bread type is known as "sliced pan", sold in 800- or 400-gram loaves, wrapped in wax paper, with the slices conveniently sized for making sandwiches and toast.
In Japan , the same half-loaf of bread is labeled by the number of slices (usually 4, 5, or 6, and occasionally 8 or 10). Thin sliced crustless "sandwich bread" is also sold in Japan, since regular 4-6 slice bread is deemed too thick.
In Canada and the United States, Texas toast is a type of packaged bread which is sliced at double the typical thickness of most sliced breads.
