Sliced Bread

Bread is an ancient food that has been eaten for tens of thousands of years. However, pre-sliced bread, which would make a bacon butty a convenient task, did not happen until the early 1900s, when a man named Otto Frederick Rohwedder of Davenport, Iowa invented a device to automate this process. He solved part of the staleness problem by wrapping the thinly sliced loaves in wax paper immediately after slicing was complete. Pre-sliced bread was a hit and within a decade people who had access to it were eating more bread per person than before. Then they began experimenting with various new ingredients and spreads to put on the thin bread slices.
