- To test Franklin’s hypothesis, naturalist Thomas-Francois Dalibard used a large metal pole to conduct electricity from lightning on May 10, 1752. In Dalibard’s writing of his Paris experiment, he concluded that Franklin’s hypothesis was right.

Jan 4, 2002 · In “Opinions and Conjectures,” July 29, 1750, Franklin made the first public suggestion by any investigator that the electrical nature of lightning could be proved experimentally. 7 The printing of this paper in Experiments and Observations, April 1751, made the suggestion available to all British electricians, but none of them was ...
Nov 15, 2017 · Franklin and Dalibard knew they weren’t getting struck by lightning but they mistakenly thought that the electricity from the cloud was “silently draining” into the pole or the key.

Jul 4, 2016 · The invention of lightning rods saved not only property but lives. Before them, the only method considered valid against thunderstorms was in hindsight insanely counterproductive: vigorous ringing of church bells in the belief that sound could break up storm clouds.
Jan 1, 2006 · The discovery that thunderclouds contain electricity and that lightning is an electrical discharge revolutionized human perceptions of the natural world, and the invention of protective rods was a clear example of how basic, curiosity-driven research can lead to significant practical benefits.
Translated and published Franklin’s first pamphlet on electricity, Experiments and Observations (1752), in which Franklin made the first public suggestion that the electrical nature of lightning could be proved experimentally. Successfully carried out the experiment Franklin had proposed (1752).
Jan 4, 2002 · Herein lies Franklin’s principal claim to priority in this great discovery. A test of lightning required the prior discoveries embodied in the “doctrine of points,” of which he was the undisputed author, and the knowledge he had gained of the role of grounding in electrical experiments.
