1770, British scientist Joseph Pliestley said: "I see a substance that is very suitable for wiping out pencil handwriting."
"At the time, the whole of Europe used rubber grains cut into small cubes to wipe away the handwriting, a substance called an eraser. Another British engineer, Edwardnaime, is thought to have invented the eraser, also for 1770 years. Before that, people used sponges to wipe off their handwriting.
Naime said he once inadvertently picked up a piece of rubber wipe handwriting, found that it worked very well, so began to produce and sell rubber wipe. The initial eraser is not convenient because the unprocessed rubber is prone to spoilage.
Until 1839, inventor Charlesgoodyear found that vulcanization can improve the quality of rubber, rubber wipe become reliable. 1858 a man from Philadelphia in the United States patented the eraser by embedding it in the tail of a pencil, but later the pencil, which was accompanied by an eraser, was patented because it was judged to be "just embedding two existing things together instead of a new product."
