Ewald Georg von Kleist

Ewald Georg (or Jürgen) von Kleist (10 June 1700 – December 11, 1748) was a German jurist, Lutheran cleric, and physicist.

A member of the von Kleist family, Ewald was born in Vietzow in Farther Pomerania. He studied jurisprudence at the University of Leipzig and the University of Leyden and may have started his interest in electricity at the latter. From 1722-1745 he was dean of the cathedral at Kammin in the Kingdom of Prussia, after which he became president of the royal court of justice in Köslin.

On 11 October 1745 he independently invented the Kleistian jar, more commonly known as the Leyden jar after Pieter van Musschenbroek of Leyden.
