It was first sold in 1928, advertised as "the greatest forward step in the baking industry since bread was wrapped". This led to the popular phrase "greatest thing since sliced bread". </P> <P> 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 sold 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 ." </P>
