That’s how it was marketed when Kleen Maid Sliced Bread was first sold in 1928. Otto Frederick Rohwedder of Davenport, Iowa invented the first loaf-at-a-time bread-slicing machine in 1912, but due to a fire destroying his prototype, the first commercial use of the machine didn’t happen until 1928. Within a year of introducing the concept, a packaging process for sliced bread had been developed and was commercially available. As it turns out, the concept of sliced bread had a significant effect on the industry. The thin pre-cut slices of bread made it easier for people to eat more slices of bread at a time, which in turn made bread a more frequent part of their diet. This increased consumption of bread, also helped increased the consumption of spreads – like jam, jellies and peanut butter. The impact was so significant that it eventually spawned the saying, the “greatest thing since sliced bread” – as a means of praising an invention or a development.
