Happy National Rubber Eraser Day! Correcting mistakes since 1770, today on April 15 commemorates the date the invention first began making written errors disappear.
Tablets of rubber (or wax) were used to erase lead or charcoal marks from paper before there were rubber erasers. Another option for the eraser was crustless bread.
A Tokyo student said, “Bread erasers were used in place of rubber erasers, and so they would give them to us with no restriction on amount. So we thought nothing of taking these and eating a firm part to at least slightly satisfy our hunger.”
• April 15, 1770, 18th-century English Separatist theologian, natural philosopher, chemist, innovative grammarian, multi-subject educator, and liberal political theorist Joseph Priestly founded a vegetable gum to remove pencil marks. He dubbed the substance “rubber.”- • 1770 English optician and scientific instrument maker Edward Nairne developed the first marketed rubber eraser.
- • 1839 American self-taught chemist and manufacturing engineer Charles Goodyear discovered vulcanization (a method that would cure rubber and make it a durable material) This method made rubber erasers standard.
- • 1858 Jamaican-born American stationer Hymen L. Lipman of Philadelphia, Pennsylvania patented the pencil with an eraser at the end.
We all make mistakes while holding a pencil in our hand, but thanks to the inventions by these men many years ago, we can erase those mistakes away.
