1928 - July 7 – The first machine-sliced and machine-wrapped loaf of bread is sold in Chillicothe, Missouri, using Otto Frederick Rohwedder's technology.

In 1928, a significant advancement in the food industry took place in Chillicothe, Missouri. On July 7th of that year, the first machine-sliced and machine-wrapped loaf of bread was sold, marking a pivotal moment in the history of bread production and packaging. This achievement was made possible by the innovative technology developed by Otto Frederick Rohwedder, an inventor who had been working on perfecting a machine that could slice and wrap bread automatically.

Rohwedder's invention revolutionized the way bread was sold and consumed. Before his machine, bread was typically sold whole and had to be sliced by hand at home or by the baker. With the introduction of machine-sliced bread, not only was the process more efficient, but it also ensured consistency in slice thickness, making it more convenient for consumers. The machine-wrapping aspect further extended the bread's freshness, reducing waste and increasing its shelf life.
