Invention of the Leyden Jar

German Ewald Georg von Kleist, invented an electricity storage device called the Leyden jar (Leiden), in 1745. Dutch physicist Pieter van Musschenbroek of the University of Leiden, discovered the Leyden Jar device independently in 1746. The basic design developed by Kleist and Musschenbroek consisted of a glass jar partly filled with water, with a cork pierced by a wire or nail that was long enough to reach the water. Static electricity travel along the wire, generated by a friction device, and accumulating in the jar. The stored charge could be released by touching the wire, producing a shock. The Leyden jar was a forerunner of the modern capacitor.
