The history of capacitors starts in the pioneering days of electricity. I liken it to the pioneering days of aviation when you made your own planes out of wood and canvas and struggled to leap into the air, not understanding enough about aerodynamics to know how to stay there. Electricity had a similar period. At the time of the discovery of the capacitor our understanding was so primitive that electricity was thought to be a fluid and that it came in two forms, vitreous electricity and resinous electricity. As you&#;ll see below, it was during the capacitor&#;s early years that all this changed.
The history starts in At the time, one way of generating electricity was to use a friction machine. This consisted of a glass globe rotated at a few hundred RPM while you stroked it with the palms of your hands. This generated electricity on the glass which could then be discharged. Today we call the effect taking place the triboelectric effect, which you can see demonstrated here powering

Ewald Jurgens (George) von Kleist, German administrator and cleric, who discovered in the leiden jar, a fundamental electric circuit element for storing electricity, now usually referred to as a capacitor. The device was independently discovered at about the same time by Pieter van Musschenbroek, who investigated it more thoroughly than Kleist. Ewald Jurgens (George) von Kleist (born in Prussian Pomerania, c. ) was the son of a Prussian district magistrate.
He studied at the University of leiden in the ′s. While a lärjunge there he may have encountered the demonstrations in experimental physics of Professor Gravesande who was involved in electricity at leiden. He apparently acquired his interest in science while at theUniversity of Leyden. Kleist returned to Pomerania to become dean or bishop of a cathedral chapter of Camin in Pomerania (now Germany). Von Kleist was a member of Prussian administrative squirearchy (or gentry), but was said to be seeking the ignition

Leyden jar
Antique electrical device that stores a high-voltage electric charge
Early water-filled Leyden jar, consisting of a bottle with a metal spike through its stopper to make contact with the water
Later, more common type using metal foil,
A Leyden jar (or Leiden jar, or archaically, Kleistian jar) is an electrical component that stores a high-voltage electric charge (from an external source) between electrical conductors on the inside and outside of a glass jar. It typically consists of a glass jar with metal foil cemented to the inside and the outside surfaces, and a metal terminal projecting vertically through the jar lid to make contact with the inner foil. It was the original form of the capacitor[1] (also called a condenser).[2]
Its invention was a discovery made independently by German cleric Ewald Georg von Kleist on 11 October and by Dutch scientist Pieter van Musschenbroek of Leiden (Leyden), Netherlands, in –[3]
