History of National Rubber Eraser Day
The eraser’s story begins in 1770 when Joseph Priestley discovered that natural rubber could remove pencil marks. Before this, people used bread crumbs to erase their mistakes. Edward Nairne began marketing rubber erasers in 1770, making them the first commercially sold erasers. The invention of vulcanized rubber by Charles Goodyear in 1839 revolutionized eraser manufacturing, making them more durable and effective.
