The year 1908 also brought to happy fruition the long and persistent
experiments of Louis Blériot, the most illustrious pioneer and
champion of the monoplane. Beginning in 1900, he had tried one type
after another, of flying machine, till he became world renowned for
his fertility of invention, his daring, his picturesque accidents and
hairbreadth escapes. So long as he was not killed he was certain to
make progress; for he had every endowment that ensures success. He
possessed the energy of early manhood, having been born in 1872; he
had the thorough technical training of the Central School of Arts and
Manufactures, where he graduated in 1895; he possessed extraordinary
talent for invention and constructional detail; he had the prowess,
courage and coolness requisite for testing intractable and dangerous
flyers; he was in the world’s most active center of aviation; he
also had sufficient means. If he was late in achieving success, it
was because he preferred to develop original ideas, and could not be
content with merely copying his predecessors.
Like many other novices in aviation, Blériot began by trying to build
a machine with flapping wings that should fly like a bird. This was to
be actuated by a carbonic acid motor. In 1904 he abandoned his first
machine, of bird type, and turned to aëroplanes, beginning with a
biplane of the Farman, or Voisin type. His second machine was built by
Gabriel Voisin, one of the most experienced of the pioneer aëroplane
manufacturers. This biplane, unprovided with an engine, was mounted
on floats, towed along the Seine by a motor boat, and rose from the
surface carrying Voisin as pilot. _Blériot III_, composed of elliptical
cells, or sustaining surfaces, and powered with two _Antoinette_
motors of 25 horse power each, was tested without success on Lake
Enghien during the year 1905-6. _Blériot IV_ was made of quadrangular
cells, and launched at Bagatelle in 1906, carrying a soldier, Peyret;
but crashed to earth in its first trial. Finally in 1907, _Blériot
V_, mounted by the inventor himself, rose into the air and flew
successfully, but was lacking in stability. His sixth aëroplane was
of the Langley type, provided with a 24-horse-power motor, then with
a 50-horse-power _Antoinette_; but it was unstable fore and aft. One
day it traversed 184 meters, then fell from a height of 25 meters and
was shattered on the ground. His seventh was one of the swiftest yet
constructed, attaining a speed of nearly 80 kilometers an hour, and, in
two private trials, covering a distance of 500 meters. Thus seven years
had slipped away, leaving Blériot still in the tentative period of his
work. But now he was at the threshold of a career of brilliant success,
which soon brought him the highest honors at home and throughout the
world.
