original semaphore
The orginal mechanical semaphore that sent messages from Paris to Toulon in 20 minutes if everyone was awake.

The Mechanical Telegraph
Long before the days of Morse Code or the telephone, the only way to send messages quickly was to use a mechanical telegraph system. These comprised a set of interconnected mechanical levers that were placed high up on a tower. These levers could be positioned in a number of ways with each combination either representing a letter or a code that could be looked up within a code book to reveal a more complex message. Shown here is a model of the Claude Chappe Mechanical Telegraph of 1792. The French created a national network based upon this system that covered a distance of 2,983 miles using 556 telegraph stations. Messages could be sent from Paris to Lille in 2 minutes and from Paris to Calais in less than 5 minutes.
Journée Découverte de la radio à Saint Lys (31) le 5 mars 2015
Chaque année, les bénévoles de l'IDRE (Institut pour le Développement des Radiocommunications par l’Enseignement) organisaient aujourd’hui une journée découverte de la radio destinée au scolaires de la région toulousaine. Au cours de cette journée, les élèves et leurs accompagnateurs ont pu faire connaissance avec avec la communication à travers la radio et l'informatique. Chaque groupe consacrait une demi-heure par atelier, et les jeunes visiteurs étaient étaient très attentifs aux propos des animateurs. Il faut ici signaler l'énergie qu'ils ont développée à transmettre leur passion.
A l'extérieur les écoliers sont passés par les ateliers de l'ARDF (radiogoniométrie sportive); l'ADRASEC (la radio et les secours) et les radio-transmissions avec le RCN-EG.. A l'intérieur ils ont approché la radio à travers les stands consacrés aux timbres, la télégraphe Chappe, la météorologie, l'électricité. La plupart ont découvert les satellites et les ballons, le morse et une station radioamateur.
Une journée qui restera dans leur mémoire.
Remercions ici encore l'IDRE pour l'organisation de cette manifestation ainsi que l'équipe de bénévoles qui assurent la logistique, l'animation et le financement. Ce type de rencontre est un exemple pour la promotion du radio-amateurisme, de la technique et des sciences d'une part, mais c'est également un modèle sur lequel certains devraient réfléchir pour en assurer le développement au niveau national.
Félicitation aux équipes de l'IDRE

Napoleons Contributions To The Postal Service
Napoleonic semaphore was the world's first telegraph network, carrying messages across 18th Century France faster than ever before. Now a group of enthusiastic amateurs are reviving the ingenious system.
Before the web, before the computer, before the phone, even before Morse code, there was le systeme Chappe.
Not for the first time or for the last, at the end of the 18th Century France made an important technological advance - only to see it overtaken by newer science.
In this case, it was the world's first ever system of telegraphy.
According to most accounts, the very word telegraph - distance writing, in Greek - was coined to describe Claude Chappe's nationwide network of semaphore.
At its most extensive, it comprised 534 stations covering more than 5,000km (3,106 miles).
Messages sent from Paris could reach the outer fringes of the country in a matter of three or four hours. Before, it had taken despatch riders on horseback a similar number of days.
But then it ended almost quickly as it began. In the 1840s and 50s, electronic telegraphy - with stations set up along the new railway lines - began to take over.
The Chappe stations disappeared into obscurity, plundered for materials and buried in vegetation.
Only in recent years has a resurgence of amateur interest permitted a handful of sites to be rescued from oblivion.
One such is the station of Mollard-Fleury, half-way up a mountainside near Modane in the Alps.
Enthusiasts worked out the probable location by consulting maps in the archives in Paris. In 2002 they found the remains of the post in woods above the village of Sardieres.
Now they have just rebuilt an exact replica, using original designs drawn up by an inspector on the line.
Visitors who make it up the brisk climb find a two-room cabin of wood and stone. The second room contains a system of wheels and pulleys, controlling the signal system which is set on a mast above the roof.
A panaromic view looks south-east across the valley to more snow-capped mountains. Beyond is Italy.
This station was part of the Lyon to Milan line that Napoleon built in 1805 as he prepared to resume war in Italy, explains Bernard Pinaud, who over the summer will give demonstrations of the semaphore.
Ultimately it extended as far as Venice, allowing the emperor to get messages to his armies in northern Italy in a matter of a few hours.
One such message has been discovered in the records of a nearby village.
It reads: The Legion of the South may recruit men in Turin from among the Piedmontese prisoners-of-war or Austrian deserters . However it must not recruit men who are not from Piedmont.
This message would have been transcribed into semaphore signs by a superintendent in Paris.
It would then have been passed down the chain of stations, each about 10km (six miles) and visible from the next.
In each hut, a single operator had the task of surveying his neighbours by telescope. As soon as there was activity, he copied down the signals and passed them on.
Of the meaning of the message, the operator had not a clue. He merely worked the machine.
Born into a family of scientists in western France, Claude Chappe (1763 - 1805) made the important observation that the human eye is excellent at discerning angles.
So he designed a system built round three parts - a long central beam, with two shorter arms attached at either end.
Each manoeuvre was reckoned to take about 30 seconds, and the messages were transmitted in full - words like de and a included. Telegram-ese had not yet been invented.
For the operators it was tiring and laborious, especially as they had pay docked for delays.
Still, by all accounts they acquitted themselves well. The record was 60 minutes for a message travelling from Paris to Strasbourg. It bore news of the birth of Napoleon's son.
We have a description of one of the Chappe stations in Alexandre Dumas's The Count of Monte Cristo, which was written in 1844 and set 30 years earlier.
The count sees the contraption like the claws of an immense beetle and feels wonder that these various signs should be made to cleave the air with such precision as to convey to the distance of three hundred leagues the ideas and wishes of a man sitting at a table.
He then bribes the operator to send false information down the network, causing a financial panic in Paris.
From the outset, the prime purpose of the system was military.
Four years into the Revolution - with fears growing of foreign invasion to restore the monarchy - the Republican government commissioned Citizen Chappe to build the first line, from Paris to Lille.
A year later, in September 1794, the government heard news - on the day it happened - that the northern border town of Conde had been captured. They telegraphed back their congratulations, which were received in Conde the very same evening.
The Great Gildersleeve: Engaged to Two Women / The Helicopter Ride / Leroy Sells Papers
Premiering on August 31, 1941, The Great Gildersleeve moved the title character from the McGees' Wistful Vista to Summerfield, where Gildersleeve now oversaw his late brother-in-law's estate and took on the rearing of his orphaned niece and nephew, Marjorie (originally played by Lurene Tuttle and followed by Louise Erickson and Mary Lee Robb) and Leroy Forester (Walter Tetley). The household also included a cook named Birdie. Curiously, while Gildersleeve had occasionally spoken of his (never-present) wife in some Fibber episodes, in his own series the character was a confirmed bachelor.
In a striking forerunner to such later television hits as Bachelor Father and Family Affair, both of which are centered on well-to-do uncles taking in their deceased siblings' children, Gildersleeve was a bachelor raising two children while, at first, administering a girdle manufacturing company (If you want a better corset, of course, it's a Gildersleeve) and then for the bulk of the show's run, serving as Summerfield's water commissioner, between time with the ladies and nights with the boys. The Great Gildersleeve may have been the first broadcast show to be centered on a single parent balancing child-rearing, work, and a social life, done with taste and genuine wit, often at the expense of Gildersleeve's now slightly understated pomposity.
Many of the original episodes were co-written by John Whedon, father of Tom Whedon (who wrote The Golden Girls), and grandfather of Deadwood scripter Zack Whedon and Joss Whedon (creator of Buffy the Vampire Slayer, Firefly and Dr. Horrible's Sing-Along Blog).
The key to the show was Peary, whose booming voice and facility with moans, groans, laughs, shudders and inflection was as close to body language and facial suggestion as a voice could get. Peary was so effective, and Gildersleeve became so familiar a character, that he was referenced and satirized periodically in other comedies and in a few cartoons.
