GENERAL SACONNEY, a military officer, a scientific and a balloonist[modifier | modifier le code]

[[3]] portrait: SACONNEY on a balloon

Jacques Theodore SACONNEY was born in 1874 in Italy (Torino) and died in 1935 in France (Dijon).

Jacques Theodore SACONNEY was a Senior French Army General, an innovative scientific and a adventurous military balloonist. He foresaw the future developments of the French military air force. His main contribution was his academic works and his activities in the development of the modern meteorology, in the creation and the promotion of the French military and civil aviation, and the developments of military kites and air photography.

Family Background[modifier | modifier le code]

Having its roots in SACONNEX, Switzerland (which is located in the suburbs of Geneva), his family escaped the Protestant Revolution by immigrating to France during the XVI century. His forefathers first settled in Lyon, where a few members of his family left some traces including Henri de SACONAY and Gabriel de SACONAY. ^[1]

The SACONAY then settled in Burgundy where they cultivated wine in Gevrey (Cote d’Or). The tombs of the family still remain in this village now called Gevrey-chambertin. During the XIXth century, Jacques Theodore’s grandfather became prosperous in the hotel industry. He followed the construction of the train between Dijon and Turin, and he ended up earning many estates in Turin, Italy, in Dijon and Aix-les-Bains, France.

A military and a scientific[modifier | modifier le code]

Jacques Theodore SACONNEY was educated at the prestigious High School Henry IV in Paris, France, and was admitted at “l’Ecole Polytechnique”, Paris, in 1895.

Appointed French army Officer in 1897, he was affected in the 4th regiment “du Génie” in Grenoble where he became a military balloonist. At first, one of his main interests lied military observation and in kites. In 1902, captain SACONNEY was successful in creating a kite system which was capable of carrying a camera that allowed the establishment of mapping.

In 1909, Théophile Bois and Jacques-Théodore SACONNEY published a scientific paper explaining the technical reasons why kits remained stable when flying in the air and providing scientific evidence explaining the equilibrium of such flying instruments.

In 1909, a competition to determine the most suitable man lifting technique existent at that time was launched. The prize was won by Captain Madiot but he died shortly in a Flying accident. As Captain Madiot’s system was not fully developed, Captain SACONNEY’s man lifting system was adopted by the French nascent Army Air force. SACONNEY’s man lifting system contained a motorcar, trailer, and a winch that was driven by the car’s engine. [[5]]

The system was also installed aboard the ship The Edgar Quintet in 1911. In November 1912, SACONNEY became head of the laboratory of meteorology and aerial photography of Chalais-Meudon. [[6]]

During the World War 1, he was in charge of the observation of the enemy. At first, he integrated a Balloonist Company, and in August 1914, Captain SACONNEY took the command of the Automobile section of the balloon and kite military section which was based in Epinal, Vosges.

Pioneer of the French Civil aviation[modifier | modifier le code]

After the Great War, Commandant SACONNEY became President of the Commission for the Application of Meteorology to Aerial Navigation, which later became the International Commission for Aeronautical Meteorology. This Commission provided guidance and coordination to international aeronautical meteorology. This Commission was part of the International Meteorological Organization (IMO), the predecessor of the World Meteorological Organization (WMO), which was established in 1919. At that time, he was reckoned to be the authority in his field.

Then he was in charge of organising the French civil aviation. Between 1919 and 1922, Colonel SACONNEY was the director of the civil aviation. In a report from the National Advisory Committee for aeronautics, entitled “commercial aviation in France” (1922), it was said that the first step of the creation of the commercial aviation in France was realised by Colonel SACONNEY. The report states that between 1919 to 1922, the French commercial aviation acquired its first experience and its supremacy by setting permanent air routes between Paris-London, Paris-Brussels, Paris-Strasbourg-Prague-Warsaw, Paris-Geneva, Bordeaux-Toulouse-Montpellier, Nimes-Marseilles, Toulouse-Casablanca, Bayonne-Bilbao.

In 1922, he rejoined the army. Became member of the Council of the French Air Force and went up in the military hierarchy.

SACONNEY died in Dijon the 14 July 1935 leaving behind him two sons and a daughter.

The last exhibition of SACONNEY’s kite was held recently in Soissons (France). The Grandson of General SACONNEY attended the event. See the photograph with the president of the Association Sportive du Cerf-volant Soisonnais (on the right)and Jean-Lech SACONNEY (on the left). [[9]]
