Otto Frederick Rohwedder (July 7, 1880 – November 8, 1960) is an American inventor and engineer who created the first automatic bread-slicing machine for commercial use. It was first used by the Chillicothe Baking Company in Chillicothe, Missouri in 1928.

Early life and education

Rohwedder was born in Des Moines, Iowa in 1880, the son of Claus and Elizabeth Rohwedder, of ethnic German descent. He was the youngest of three brothers and a sister Elizabeth.

When a child, Rohwedder and his family moved to Davenport, where he lived until the age of 21. He attended Davenport public schools. Then he became an apprentice to a jeweler to learn a trade.

Rohwedder also studied optometry, graduating in 1900 with a degree in optics from what is now the Northern Illinois College of Ophthalmology and Otology in Chicago. He became a jeweler.

Marriage and family

Rohwedder married Carrie Johnson in 1905. They settled in St. Joseph, Missouri and had two children.[1]

Career

Rohwedder first had a chief career as a jeweler, and became the owner of three jewelry stores in St. Joseph. His used his work with watches and jewelry to create inventions of new machines. Convinced he could develop a bread slicing machine, he sold his jewelry stores to fund the development effort and manufacture the machines.[1] In 1917 a fire broke out at the factory where Rohwedder was manufacturing his machine. It destroyed his prototype and blueprints. With the need to get funding again, Rohwedder was delayed for several years in bringing the bread slicer to market.[2]

In 1927 Rohwedder successfully designed a machine that not only sliced the bread but wrapped it. He applied for patents to protect his invention and sold the first machine to a friend and baker Frank Bench, who installed it at the Chillicothe Baking Company, in Chillicothe, Missouri in 1928. The first loaf of sliced bread was sold commercially on July 7, 1928. Sales of the machine to other bakeries increased and sliced bread became available across the country.[2]
