The eraser

On April 15 1770 the noted scientist Joseph Priestley recorded the following sentence: "I have seen a substance adapted from paper that cleans the mark of black lead pencil". Then the English Engineer, Edward Naime is also credited with the creation of the first eraser in 1770.
Before the rubber, breadcrumbs had been used to erase pencil marks.
In 1839, Charles Goodyear discovered a way to make the rubber a useable material, and then in 1844, he patented its process.
