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