Ewald Georg von Kleist

A member of the von Kleist family, Ewald was born in Wicewo in Farther Pomerania.

His father was district administrator Ewald Joachim von Kleist [de] (1657–1716).

From 1722–1745 or 1747[citation needed] he was dean of the Cathedral of St. John the Baptist [de] in Kamień Pomorski, in the Kingdom of Prussia, after which he became president of the royal court of justice in Köslin.

Influenced by Georg Matthias Bose,[1] he independently invented the Kleistian jar on 11 October 1745, which could store electricity in large quantities.

He communicated this discovery to a group of Berlin scientists in late 1745, and the news was transferred in a confused form to Leyden University where it was further investigated.
