Although
little known outside of his native France, Charles Cros (1842-1888) truly was one of the
great visionaries of an age of visionaries. He has been described as a
figure of transition between the reign of poetry and the
patent. A well regarded of poet and writer of humorous stories on one
hand and a creative inventor on the other. As an inventor, however, he
may also be described as one of the unluckiest.
On the same day in 1869, Charles Cros and Louis Ducos de Hauron, without knowledge of one another sent news of their identical inventions of colour photography to the Soci?t? fran?aise de photographie. Cros'
documentation of proof which had been lodged in a safety deposit box had predated Ducos de Hauron's by nearly a year
(although both had been working on the subject for longer than that)
but the latter had produced actual samples using this method. The two
settled the matter on amicable terms but Ducos de Hauron is now
considered to be the inventor of colour photography.
Nearly a decade later, in 1877, Cros presented to the Academy of
Sciences a method for the recording and playing back of sounds using
his new invention - the phonograph. Later that year, Thomas Alva Edison,
demonstrates his own version of the same idea and successfully patented
it in early 1878. Despite of Cros' protests, his contribution was once
again forgotten.
One area where Cros is still remembered is with regard to his proposal
for interplanetary communication. He presented to a conference in 1869,
a "Study on the means of communication with the planets" in which he
proposed a method of communication with the inhabitants of Mars and Venus.
His idea revolved around using an extremely bright light concentrated
by an array of parabolic reflectors (these days communication through
space is achieved with radio waves but these are, after all, really the
same thing). Images could be transmitted by breaking them up into
individual pixels, either on or off, and then sending them a line at a
time using an encoding that these days we would call run-length encoding.
The declaration of Ordinance 97 of the
32nd Grand Master of Terrestrial Astronomy raised a flurry of
complaints by the goguenard party. Let me say right away that
this
party, though it is often furiously defended, calls to mind the
wrongheaded beliefs of the free-thinkers that were in
favour a few centuries ago. So much so that one fears seeing it going to same negative excesses which consequently would
require same repressions.
Indeed, one would have to be unfamiliar with even
the most elementary
study of administrative law not to know the formalities required by all
observatory councils with admission to observatories of correspondence. It
is necessary not to have read any astronomical publication from this
century to be unaware of the Code of the Observatory of which
this much criticised ordinance is all about. The reality is that the Code
is already commonly used and has been expressly employed in
many official documents, some dating back a great many years.This director, exceptionally even for the time, had married. To tell you the truth, he was a widower during his term but there remained to him a son of twenty two or twenty three years of age.
One thus carried out the exchange of the Venusian and
terrestrial
botanical specimens, and the array was constantly pointed at the peak
of a particular Venus
mountain (the location of which is useless for me to indicate). The
director, absorbed by the
powerful interest of his research, had the idea, a rather unfortunate
one we may say in retrospect, of using the assistance of his son for
the fixing and classification of the photographs that were being transmitted to him.
One day Glaux, having finished the day's transmission,
was about to
take his leave when he saw, walking out upon the terrace of the
Venusian
observatory, a being which he did not recognise as one of the personnel
up
there.Taking account of the distinctions and the
restrictions in our scientific understanding, I will say, to keep it
simple, that this being was a woman.
It was from
this day that one saw Glaux putting such zeal and ingenious
activity into his functions as correspondent. Did he conceive of by
himself these marvelous innovations which
we now take for granted and still use to this day? Or did he learn of
them through communication with her? Were they perhaps indiscretions,
most advantageous for us, of the young Venusian not terribly concerned, as
so often is the case with women, to
carefully guard the scientific secrets of her planet.
The third year was terrible, a turbulent storm
of rapture and
despair... Could one have saved the foolish pair at this
time by drastic measures? It is doubtful, the damage by now had already
been done.
