The BEP engraved the vignette Franklin and Electricity (c. A more complete account of Franklin's experiment was given by Joseph Priestley in 1767, who presumably learned the details directly from Franklin, who was in London at the time Priestley wrote the book. This account was read to the Royal Society on December 21 and printed as such in the Philosophical Transactions. Franklin described the experiment in the Pennsylvania Gazette in October 19, 1752, without mentioning that he himself had performed it. Franklin's kite experiment įranklin's kite experiment was performed in Philadelphia in June 1752, according to the account by Priestley. However, the spire at Christ Church was not added until 1754. Franklin himself is said to have conducted the experiment in June 1752, supposedly on the top of the spire on Christ Church in Philadelphia. An attempt to replicate the experiment killed Georg Wilhelm Richmann in Saint Petersburg in August 1753 he was thought to be the victim of ball lightning.
Such an experiment was carried out in May 1752 at Marly-la-Ville in northern France by Thomas-François Dalibard. In 1752, Franklin proposed an experiment with conductive rods to attract lightning to a leyden jar, an early form of capacitor. The physicist Jacques de Romas also wrote a mémoire with similar ideas that year, and later defended them as independent of Franklin's. The same year, Franklin reversed his previous skepticism of electrical lightning's attraction to high points.
In 1750, it was the subject of public discussion in France, with a dissertation of Denis Barberet receiving a prize in Bordeaux Barberet proposed a cause in line with the triboelectric effect. Speculations of Jean-Antoine Nollet had led to the issue of the electrical nature of lightning being posed as a prize question at Bordeaux in 1749. 3.1 The Pennsylvania Gazette 's account.
