A lightning rod or lightning conductor (British English) is a metal rod mounted on a structure and intended to protect the structure from a lightning strike. If lightning hits the structure, it is most likely to strike the rod and be conducted to ground through a wire, rather than passing through the structure, where it could start a fire or ...
The experiment was first proposed in 1752 by Benjamin Franklin, who reportedly conducted the experiment with the assistance of his son William. The experiment's purpose was to investigate the nature of lightning and electricity, which were not yet understood. Combined with further experiments on the ground, the kite experiment demonstrated that ...
The famous kite experiment enabled the Philadelphia group to established what had been surmised by others, that lightning was identical to the mild charge of electricity produced by the friction of the electrostatic machine. Franklin invented the lightning rod, which goes down in history as the first practical electrical invention.
In May 1752, Dalibard affirmed that Franklin's theory was correct. Around June 1752, Franklin reportedly performed his famous kite experiment. The kite experiment was repeated by Romas, who drew from a metallic string sparks 9 feet (2.7 m) long, and by Cavallo, who made many important observations on atmospheric electricity.
Franklin observed that lightning frequently destroyed homes by igniting those made of wood. Franklin was determined to prove the presence of electricity in lightning through an experiment. Franklin's experiment, in its initial conception, depended on the completion of Christ Church in Philadelphia , whose steeples would be sufficiently high as ...
1752 – Benjamin Franklin establishes the link between lightning and electricity by the flying a kite into a thunderstorm and transferring some of the charge into a Leyden jar and showed that its properties were the same as charge produced by an electrical machine. He is credited with utilizing the concepts of positive and negative charge in ...

Now seen as a visionary inventor, supporters see him as the European inventor of the lightning rod, who invented the lightning rod in the same years as Benjamin Franklin, probably even independently. Despite scientific reviews of Diviš's errors (among others, German physicist Meidinger, who compared evidence about early lightning rods in 1888 ...
