What product is Otto Frederick Rohwedder's most famous invention for?

Otto Frederick Rohwedder (July 28, 1880 – November 8, 1960) was an American inventor and engineer who created the first automatic bread-slicing machine for commercial use. It was first used by the Chillicothe Missouri Baking Company. In 1927 Rohwedder successfully designed a machine that not only sliced the bread but wrapped it. He 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.

Rohwedder had a brief career as a jeweler, and became the owner of three jewelry stores in St. Joseph, Missouri. He used his work with watches and jewelry to invent new machines. Convinced he could develop a bread slicing machine, he sold his jewelry stores to fund the development effort and manufacture the machines.

In 1930 Continental Baking Company introduced Wonder Bread as a sliced bread. It was followed by other major companies when they saw how the bread was received. Later that year, Rohwedder sold his patent rights to the Micro-Westco Co. of Bettendorf, Iowa and joined the company. He became vice-president and sales manager of the Rohwedder Bakery Machine Division.
