Electricity -- Biography
M. de Romas lived in Nérac, a small town some seventy-five miles south
of Bordeaux. He was a member of the bar; and at the time of the
Franklinian furor in Europe was a judge of the district court. He took
an interest in scientific matters quite unusual for men of his
profession, proceeding, as soon as he had read of the efficiency of
pointed conductors, to study their behavior for himself. His experiments
met with surprising success, and were as much admired by the local
savants as they were dreaded by the common folk. Letters containing his
observations were regularly sent to the Academy of Bordeaux, where they
were read with lively interest on account of their character and
novelty. From the published _Actes_ of that body we learn that the first
kite used by de Romas was raised by him on May 14th, 1753.
Disappointment, however, attended this attempt, no electrical
manifestation being observed, although rain fell and wetted the hempen
cord. The magistrate of Nérac attributed his failure to the resistance
of the string; and, like a good electrician, surprisingly good for the
time, determined to improve its conductivity by wrapping a fine copper
wire round its entire length. When this long and tedious operation was
completed, he went out again to the fields on a stormy day, when,
assisted by two of his friends, he raised the kite and soon got torrents
of sparks from the wire-wound cord. This was on June 7th, 1753. The
experiment was repeated from time to time, both for his own satisfaction
and that of his assistants as well as for the entertainment of his
ever-growing class of admiring spectators. Kites 7-1/2 ft. long and 3
ft. wide were raised 400 and even 550 ft. above ground when flashes nine
feet long and an inch thick were drawn, so the account says, with the
report of a pistol. The effect must have been truly spectacular. The
kite was held by a silk ribbon fastened to the end of the hempen cord.
It is then a matter of history vouched for by the _Actes_ of the Academy
of Bordeaux that May 14th, 1753, is the day on which the first use of a
kite for electrical purposes was made in France; on the other hand, it
is to be remembered that Franklin flew his "lightning kite" in June,
1752, almost a year earlier. As far, then, as the _fact_ is concerned,
the Philadelphia philosopher was not anticipated by the Justice of
Nérac.
From facts let us pass to writings. Franklin's letter to Collinson, in
which he describes the electric kite, is dated October 19th, 1752, while
that of M. de Romas, on which the claim for priority is founded, was
addressed by him to the Academy of Bordeaux on July 12th, 1752, three
months earlier. After a lengthy and interesting account of his
experiments with pointed conductors, he concludes his communication as
follows:
