National Rubber Eraser Day - April 15


Observed annually on April 15 is National Rubber Eraser Day.  This day celebrates, recognizes and appreciates the invention of erasers.

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, Joseph Priestly founded a vegetable gum to remove pencil marks.  He dubbed the substance “rubber.”
  • 1770 Edward Nairne developed the first marketed rubber eraser.
  • 1839 Charles Goodyear discovered vulcanization (a method that would cure rubber and make it a durable material)  This method made rubber erasers standard.
  • 1858 Hyman Lipman (Philadelphia, Pa.) 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.
