In 1770, a scientist was handling a lump of rubber and found it rubbed pencil away, leading to the creation of the eraser, changing every school desk

A pivotal moment in 1770 came when Joseph Priestley noted that natural rubber could easily wipe away graphite marks from paper. A material well-known to indigenous communities, Priestley's revelation opened the door to the invention of the eraser. This simple tool turned writing mistakes into manageable corrections, fundamentally changing the approach for everyone from schoolchildren to professional authors.
