Sandpaper was patented in the United States
On this day · 14 June 1834
A Vermont inventor won the first U.S. patent for manufacturing sandpaper, formalizing an abrasive that woodworkers still reach for daily.
On 14 June 1834, Isaac Fischer Jr. of Springfield, Vermont, received U.S. patent X8,246 for a process of manufacturing sandpaper. His method bonded an abrasive grit to paper, turning a crude, irregular craft material into something that could be produced to a consistent standard.
Fischer was not the first person ever to glue grit to a backing — versions reach back to 13th-century China, where crushed shells and sand were fixed to parchment with gum. What he patented was a repeatable industrial process, the step that let factories rather than individual artisans churn out the stuff.
The patent carries an “X” prefix because it predates the great U.S. Patent Office fire of 1836; surviving records of these earliest patents were later restored and renumbered with that mark.
Nearly two centuries on, the basic idea is unchanged. Every sanding block, nail file, and furniture refinish still relies on Fischer’s elegantly dull insight: grit, glue, paper.
