Rohwedder was a jeweler from Davenport, Iowa. His world was tiny gears, watch
springs, precision tools. Then he walked into a bakery long enough to see the
problem. Bread was sold whole, hacked into slices at home, crumbly and uneven.
He thought, “There ought to be a better way.” Something mechanical that could
do the job once and do it perfectly.Otto Rohwedder spent over two decades perfecting
the invention that made sliced bread possible
Around 1912, he sold his jewelry business to
bankroll it, a decision most people called insane. “Bread can’t be sliced by
machine,” bakers told him. “It’ll go stale before you can sell it.” Rohwedder
didn’t argue. He built it anyway. His wife, Carrie, said, “He wasn’t the kind
to quit when he got told no.”
He worked in a basement filled with bread crumbs
and cutting tools. He measured loaf dimensions with calipers, built frames of
steel, gears that turned too fast, and blades that jammed on crusts. The loaves
fell apart. He added holding pins. He invented a mechanism that would slice and
then clamp the bread back together until it could be wrapped. “A sliced loaf is
like a family,” he said. “It needs to be held together, or it falls apart.”
