who invented sliced bread

Otto Frederick Rohwedder, an American inventor from Iowa, is credited with inventing the first practical bread‑slicing machine that led to what we now call sliced bread.

Quick Scoop

  • The question “who invented sliced bread” usually refers to the person who invented the automatic bread‑slicing machine used in bakeries, not to the first person who ever sliced bread with a knife.
  • That inventor was Otto Frederick Rohwedder, a jeweler‑turned‑inventor who spent years developing a machine that could slice loaves evenly and wrap them for sale.
  • The first commercially sold pre‑sliced bread using his machine appeared on July 7, 1928, at the Chillicothe Baking Company in Chillicothe, Missouri.

Mini History: From Idea to “Best Thing”

  • Rohwedder began working on the concept of an automatic bread slicer around the early 1910s and even sold his jewelry stores to fund the project.
  • A fire in 1917 destroyed his early prototype and blueprints, forcing him to rebuild the design before finally producing a reliable machine in the late 1920s.
  • When the Chillicothe Baking Company installed his machine and started selling “Kleen Maid Sliced Bread,” local ads promoted it as the greatest leap in baking since wrapped bread, inspiring the modern phrase “the best thing since sliced bread.”

Why It Was Such a Big Deal

  • Pre‑sliced loaves made sandwiches, breakfasts, and school lunches faster to prepare, which quickly boosted bread consumption in the United States.
  • The convenience of uniform slices also helped popularize home toasters, since the machine‑cut slices fit and toasted more evenly than hand‑cut bread.

Little Extra: First Bakery & Modern Legacy

  • The Chillicothe Baking Company is widely recognized as the first bakery in the world to sell packaged sliced bread, and the town still promotes itself as the “Home of Sliced Bread.”
  • By the early 1930s, large brands like Wonder Bread adopted and marketed sliced bread nationally, and by 1933 sliced bread outsold unsliced loaves in many American bakeries.

TL;DR: Otto Frederick Rohwedder invented the bread‑slicing machine, and sliced bread first hit store shelves in 1928 at the Chillicothe Baking Company in Missouri.
