Static electricity was first described by the ancient Greek philosopher Thales of Miletus around 600 BCE, when he noticed that rubbed amber could attract small bits of straw and other light objects.

Early discovery

  • Around 600 BCE, Thales observed that rubbing amber caused it to attract light materials, one of the earliest recorded observations of what is now called static electricity.
  • The Greek word for amber, ēlektron , later gave rise to the modern word “electricity,” linking his observation directly to the term used today.

Later understanding

  • Much later, in the 1600s, William Gilbert studied these amber effects systematically and helped establish electricity as a distinct field of natural philosophy, but he did not make the original discovery of static electricity itself.
  • Over the following centuries, scientists such as Charles du Fay and Charles Coulomb developed the ideas of two types of charge and quantitative laws for electrostatic forces, turning Thales’s simple observation into a mathematical science.
