"My father thought America was the greatest thing since sliced bread.... sliced bread having been invented the previous winter." - Grampa Simpson, "The Simpsons"
In 1912, Otto Frederick Rohwedder of Davenport, Iowa invented the first single loaf bread slicing machine, but his prototype was destroyed in a fire. It wasn't until 1928 when he had a fully working machine ready. The first commercial use of the bread-slicing machine was by the Chillicothe Baking Company in Chillicothe, Missouri, who sold the first loaf of sliced bread on July 7th, 1928. By 1933, approximately 80% of bread sold in the United States was pre-sliced, leading to the popular idiom, "the greatest thing since slcied bread".
