Leyden Jars

The Leyden jar was invented in Leyden, a city in the Netherlands, separately by two different men, German cleric Ewald Georg von Kleist and Dutch scientist Pieter van Musschenbroek in 1745.

Leyden jars store and discharge static electricity for scientific experiments. They were also used in some of the first attempts to apply electricity for medical purposes.

Benjamin Franklin attempted to cure paralysis and limb dysfunction with jolts from a Leyden jar, but with little permanent success. The gold leaf in the Leyden jar increases its capacity to hold a static charge.
