How was electricity discovered?

Michael Faraday, Luigi Galvani, Alessandro Volta, Andre-Marie Ampere, and Greg Ohm did work that provided the basis for modern electrical engineering.
Italian physician Girolamo Cardano returned to the subject of electricity in De Subtilitate (1550) distinguishing, perhaps for the first time, between electrical and magnetic forces. In 1600, the English scientist William Gilbert coined the modern Latin word ‘electricus’ from ‘elektron’, the Greek word for ‘amber’ which soon gave rise to the English word – electricity.
Otto von Guericke invented an early electrostatic generator in 1660. Other European pioneers were Robert Boyle, who in 1675 stated that electric attraction and repulsion can act across a vacuum. Stephen Grey, who in 1729 classified materials as conductors and insulators, and C. F Du Fay, who first identified the tow types of electricity that would later be called positive and negative.
