Who perfected the machine that could both slice and wrap an entire loaf, and when was the first sliced bread sold?
Answer
Otto Frederick Rohwedder in 1928
The key agent responsible for introducing the convenience of pre-sliced bread was Otto Frederick Rohwedder. Rohwedder successfully developed and perfected a mechanism that performed two crucial functions simultaneously: it could slice an entire loaf of bread uniformly and immediately wrap the slices securely. This integrated system was first commercially implemented and sold in Chillicothe, Iowa, in the year 1928. This invention marked a significant departure from prior methods where bread was purchased whole, requiring the consumer or home cook to undertake the manual and often uneven task of slicing.
