A Leyden jar, or Leiden jar, is a device that "stores" static electricity between two electrodes on the inside and outside of a glass jar. It was the original form of the capacitor.
It was invented independently by German cleric Ewald Georg von Kleist on 11 October 1745 and by Dutch scientist Pieter van Musschenbroek of Leiden (Leyden) in 1745–1746. The invention was named for this city.
The Leyden jar was used to conduct many early experiments in electricity, and its discovery was of fundamental importance in the study of electricity. Previously, researchers had to resort to insulated conductors of large dimensions to store a charge. The Leyden jar provided a much more compact alternative.

Famous quotes containing the word jar:
“As soon as you begin to say “We have always done things this way—perhaps that might be a better way,” conscious law-making is beginning. As soon as you begin to say “We do things this way—they do things that way—what is to be done about it?” men are beginning to feel towards justice, that resides between the endless jar of right and wrong.”
—Helen M. Cam (1885–1968)
