Franklin, Benjamin, 1706-1790; Statesmen -- United States -- Biography
I am told by a specialist that the neatness and thoroughness of the
reasoning by which Franklin established his theory before proceeding to
experimentation are most laudable, and I am sure his letters of
explanation have a literary charm not often found in scientific
writing. The paper in which Franklin developed his theory and showed
how it might be tested by drawing lightning from the clouds by means of
a pointed wire set up on a steeple, was sent to his friend in England,
and there printed; and at the suggestion of the great Buffon the same
paper was translated into French. The pamphlet created a sensation in
France, and the proposed experiment was actually performed in the
presence of the king. Before the report, however, of the successful
experiment reached Franklin he had himself verified his theory, using a
kite to attain an altitude, as there was no spire or high building in
Philadelphia. Taking his son with him, he went to an old cow house in
the country, before a storm, and there, to catch the electric fluid,
sent up his kite made of an old silk handkerchief. A wire extended from
the upright stick of the kite, and this was connected with the cord,
which when wet acted as a good conductor. The part of the cord held in
his hand was of silk, and between this and the wet hempen cord a key
was inserted and connected with a Leyden jar. How successful the
experiment proved to be, all the world knows. Somehow all the important
events of Franklin's life are dramatic and picturesque, and this scene,
especially, of the philosopher in the storm drawing down the very
thunderbolts of heaven has always had a fascination for the popular
mind. The detailed story of the experiment became public only through
Franklin's conversation with his friends. When he learned that his
theory had been previously verified in France, his modesty was so great
that in writing he simply told how the experiment might be performed
with a kite, never that he himself had actually accomplished it. In
consequence of this discovery he was at once elected a member of the
Royal Society of London, Yale and Harvard gave him the honorary degree
of master of arts, and everywhere he was celebrated as the foremost
philosopher of the day.
