The experiment of Benjamin Franklin in drawing, as he thought, the electricity of stormclouds to the ground by his kite, and thereby demonstrating the necessity for the establishment of lightning conductors, for the protection of persons and buildings, was accepted as thoroughly satisfactory by the whole scientific world of Europe at that time. Franklin was wrong, however, in supposing that the lightning had really passed along his kite-string from the clouds to the earth, for, had this been the case, he would undoubtedly have been killed. What he witnessed was merely the inductive action of the thundercloud on the kite and string. There had been some doubts in respect to the experiment made, at the suggestion of Franklin’s pamphlet, at Marly-la-Ville, since all the witnesses were inexperienced persons, entirely unacquainted with the phenomena of electricity; but there could be none whatever as regarded that tried by the originator himself, and pronounced satisfactory by him. The fame of the wonderful discovery spread with extraordinary swiftness through the civilized world. Praises and congratulations flowed in upon the hitherto obscure citizen of Philadelphia from all sides. The king of France sent him a letter, full of compliments; the Royal Society of London voted him their gold medal, modestly claiming a share in his work; and nearly all the scientific bodies of France, Germany, and Italy elected him an honorary member. But the praise of which Franklin had most reason to be proud came from the great philosopher Immanuel Kant. The sage of Königsberg grandly called him the modern Prometheus, bringing fire from heaven.
