Today in History, July 7: 1928 – “The best thing since sliced bread.” In 1912 Otto Frederick Rohwedder of Davenport, Iowa invented a machine to automatically slice bread, but it was destroyed in a fire. It would take him until 1928 to perfect his machine, first used by the Chillicothe Bread Company of Chillicothe, Missouri on this date. With bread pre-sliced to smaller dimensions, sales went wild, except for a brief 2 month interlude when pre-sliced bread was banned during WWII to lower prices. The ban was lifted after complaints from mothers.
