Edward Nairne first developed the the eraser and it was widely used. However, these rubbers used to go bad after a certain length of time. Hymen Lipman received the first patent for attaching a rubber to the end of a pencil.
in 1770 the eraser was made
eraser was not invented but discovered by an unknown person
Natural rubber was used as an eraser at least as early as 1770, but it was perishable and 'went bad' after a short time. Charles Goodyear developed the vulcanization process which made the kneaded eraser practical in 1839.
The eraser was first added to the end of pencils in the 1850s. Prior to this, people used separate pieces of gum or rubber to erase pencil marks. The combination of the pencil and eraser became popular with the invention of the first mass-produced pencil with an attached eraser by Hymen Lipman in 1858. This innovation helped streamline the writing and correction process.
Edward Nairne, in 1770, invented the first rubber eraser.
Edward Nairne was born in 1726.
Nairne invented the rubber eraser after the discovery of rubber in 1770. He sold them in England, at a high price. Each half inch cube was three shillings. This is how the eraser, or rubber, got its name, that it rubs out pencil marks. It is interesting to note that Edward Nairne and Edward Naime are the same people. His last name has not been determined, since he lived so long ago, the written name cannot be determined as an "M" or "RN."
