Fundamental Reflections On Chadeau Inclusive Of The Context And Nature Of His Work

Emmanuel Chadeau was primarily an economic historian, focusing on the economic and industrial development of France, with a fairly strong emphasis on aviation, in the context of these other emphases. Aside from his own prolific writing, he presented the writings of others, studies were conducted, under his direction, and the output of several colloquia were published, these colloquia occurring under his direction. In his capacity as faculty at Lille III, he also oversaw a great number of Master's theses. We are gradually working this complex out, by degrees, and as variably pertinent to his analyses of aeronautical development.

(For a developing summation of his overall historical analysis, as it pertains to our interests, see the material below, drawn from the unpublished version of his Doctoral dissertation, likely to be cross-referenced with the published version.)

(The other publication and academic titles we have here were drawn from a document FONDS EMMANUEL CHADEAU, given to us by a librarian at Lille III. Many names recur in the dynamic of these publication, with the role of Chadeau playing variably relative to the recurrent names of other scholars, such as Pierre Birnbaum. These "FONDS" also contain a great output of other scholarly work. To the work less directly touched by Chadeau himself we are more strictly applying the criteria of aero-relevance, and relevance to the period we are studying. We are being more broadly inclusive of Chadeau's own work, and that most directly directed by him. He did write beyond the aeronautical field, and he did write on aeronautical subjects as they developed after the years we are studying. We are giving him fairly complete coverage, as an individual, giving context to his more directly pertinent analyses. His works touched upon industrial property law as a context affecting the title "inventor"(ingénieur), on statist developments are administrative channels, specifically as they affected aeronautical progress, among vastly other things, and is of extraordinarily broad pertinence to our work.)

We are looking into Chadeau's several other published works. His collection of works, by others, many having to do with France's trajectory of industrial capital, some with a specific emphasis on aviation, is also of note. In his capacity as a faculty member at Université Lille-III, he did this collecting, pertinent to us, and he also oversaw the Masters' these of another generation.

Material Drawn From The Unpublished Version Of Chadeau’s Doctoral Dissertation

(Thèse Pour le Doctorat ES-Lettres et Sciences Humaines, Université de Paris-X-Nanterre, Octobre 1985)

État, Entreprise & Developpement Économique : L’Industrie Aéronautique en France (1900-1940)

There are five volumes to this, with “Parties” largely corresponding to these volumes. though Volume 2 includes both the “Deuxième Partie : Naissance de l’Entreprise Aéronautique (1900-1914)” and the “Troisième Partie : Prospérité, Affaires et Bureaucratie (1914-1918)”.

Volume 1, after acknowledgements, a photographic dossier, and a general introduction, gets into the “Première Partie : L’Industrie Jusqu’en 1940, Étude d’Ensemble”.

On the ground, as it were, at Lille-III, presented with the unpublished version of this dissertation, we focused on Volume 2, on the included “Deuxième Partie : Naissance de l’Entreprise Aéronautique (1900-1914)”. This opens with the assertion that it was between 1905 and the middle of 1909 that aviation arose, as an economic force, that is, with the simultaneous putting in place of the first builders of heavier-than-air, the professional organization of the entrepreneurs, and foresight regarding an emryonic market. Finally, there appeared the first connections between the “pôle d’activité” and the surrounding economic milieu.

(Stylistically and otherwise, this section of the dissertation is of note in that, while titularly emphasizing key early XXth Century developments, of the transition from invention, as such, and movements towards greater industrial scale, it also features a friendly and succinct summation of the preceding history, from work following that of the Frères Montgolfier, through the XIXth Century, up to the developments preceding the Great War.)

This is treated as a “crystallization” which was the fruit of long preceding evolution. The work thusly gets into some fine handling of Late-19th Century historical also of great interest.

This crystallization brings with it the distinguishing between methods of experimentation pertinent to motorized and non-motorized aircraft. One characteristic of this time is the separation of private initiative from the state. This founds the separation of enterprise from the state until 1936 and explains the essential traits of the industry until 1914, or even 1918 or 1920.

Crossed out of the unpublished material is a section on a check in military research taking place between 1880 and 1905 (p.164), though a mere title change is penciled in, and a changing of the timespan to 1899-1910.

The text starts with an analysis of the trajectory of dirigibles, alleging, at this point, aeronautic research being assured by the army, in the late 19th Century, this support being a rebirth of the tradition which had begun in the late 18th Century.

This earlier history is fleshed out, inclusive of the fundamental leap made between the balloon and the dirigible, the experimentation with the “Montgolfière” en November and December of 1793, conducted by Jean-François Pilâtre de Rozier, of the Marquis d’Arlandes, and of the doctors Charles and Robert, the latter an officer in the Corps des Ingénieurs - the future Génie - the Lieutenant Jean-Baptiste Meusnier proposed the employment of balloons, driven by propellers, in the furtherance of military observations. (The term “Montgolfière” was naturally applied to aircraft based upon the balloon type invented by the Frères Montgolfier.)

Due to financial and technical difficulties, this aircraft was not constructed, but the idea of controlling air, in the furtherance of military command decisions, progressed. Meusnier was killed in June 1793, but his projects were continued under the leadership of Cassell, in collaboration with notables such as Louis-Bernard Guyton de Morveau, Antoine Laurent Lavoisier and Jean-Marie Coutelle being involved in the efforts.

These men focused on improvements to captive balloons, and a process of hydrogen gas fabrication by way of iron oxidation. Work with dirigible design was abandoned in favor of further improvement in "Montgolfière" balloons, but the concept of fabrication of the "envelope", itself, was able to progress.

It is Lhomond who, in October 1793, presents at the Tuileries a captive balloon prototype, produced by the French government, at the expense of an seized expatriate. He was convinced that an operational captive balloon would be produced. This aircraft appeared in June 1794 near the troops of Sambre and Meuse. Instructions specified its use in advance, but it was hoped that its appearance would bring an impression of terror, so as to discourage the enemy, or worse. From the 23rd to the 26th of June, 1794, these objectives were able to be attained.

The Armée de Jourdan (a French army hailing from France’s south) then captured and illicitly took this craft from Charleroi, Belgium, and took it to Fleurus (that is, slightly to the northeast).

Subsequently, and in a manner more pertinent to us, ten of these balloons were constructed, and on the 31st of October, 1794, an École National d’Aérostation was established, at Meudon, a bit to the west of Paris. … … …


… … …

Later comes material on the corporate evolutions following the early ateliers, particularly those associated with Appareils d'Aviation Les Frères Voisin, and with the Société Antoinette, the rises and falls in statist military-industrial support of the research engaged in by Clément Ader, the latter’s well-known formative work with the “heavier-than-air”, thoughts on Clément Ader, relative to the French military. For Ader's own writing on related subjects, see Ader, 1908, L'Aviation militaire.

The role of the French state, heavily tangent both to the military, of course, and to industry more generally, as furthering or hindering the progressive impulses of the aeronautic pioneers, is always pertinent.

There was support for Ader's “doctrine of usage”, of his Avions serving the army with intelligence, attacking enemy combattants on the ground, bombing and infiltrating enemy territory from behind. It was a Minister of War, Général Billot, who decided to suppress all of Ader's “subventions”, on 8 February 1898. See Jean-Baptiste Billot on French Wikipedia

Chadeau's Figure 57, on page 180, offers a diagram, and an explanation, articulating the dynamics of aeronautical development, inclusive of subcategories, relative to funding, the state, the military, and relative to other industries. All of this is penciled out. We are uncertain as to permanent inclusion, exclusion, or variation of the material in the published version. We are documenting his thought processes, over time, relative to our other manners of data tracking.

Works of Chadeau himself and published scholarship conducted under his direction

Other Material Collected By Chadeau And Reflective His Analyses

(Our interests here include the status of the inventor, perspectives on the rise, or fall, of the innovative spirit, per se, the role of "ateliers", as dynamic precursors to later types of industrial organizations, and the role of the state, that is, the role of planning, in relation to individual initiative, all of these, along with other factors, as they indirectly, or quite directly, affect the aeronautic trajectory which is our focus.)

Licences

A significant number of papers fitting this designation were put out, under the Chadeau’s direction, often direction shared with one or two other faculty. A few of these, listed within the FONDS EMMANUEL CHADEAU, make no mention of Chadeau. Aero-pertinence is patchy, but we are keeping this data on hand.

Maîtrises

Aside from Chadeau’s own Maîtrise, grouped here presently in keeping with the Lille III data we have uncovered, a significant number of theses fitting this designation were put out, under the Chadeau’s direction, often direction shared with one or two other faculty. A few of these, listed within the FONDS EMMANUEL CHADEAU, make no mention of Chadeau. This data is found elsewhere online. We are presently including only a few of these.
