33. Rôle d'Honneur
A Radio Talk by Charles F. Kettering
A country that produces great music, as a
rule, also makes important contributions to science and invention. In
this intermission, I should like to mention briefly some of the
accomplishments of French engineers and scientists which have had a
great and lasting influence on world progress.
The Italian Leonardo da Vinci was
one of the first to experiment with flying machines in about 1500, but
for nearly 300 years no progress was made until in the Montgolfier
brothers constructed a balloon which rose to a height of 6000 feet.
A short time later another Frenchman, de
Rozier, made the first human flight; and only two years after the first
flight, Blanchard crossed the English channel in a balloon. Ten years
later Blanchard came to America
and flew from Philadelphia, across the Delaware River into New Jersey.
He carried and delivered the first air mail.
French inventors also contributed much to transportation on the ground.
In nearly every history dealing with self-propelled road vehicles, you
will find the name Nicholas Cugnot.
Cugnot was a French artillery officer and built a three-wheeled steam
propelled vehicle to pull artillery. Its chief difficulties were that
it had to be refueled every 15 miles and turned over very easily.
Because of these faults, the inventor was driven into exile.
