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summation of his overall historical analysis, as it pertains to our interests, see the material below, drawn from the unpublished version of his Doctoral dissertation, likely to be cross-referenced with the published version.)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

The Published Version Of Chadeau's Doctoral Dissertation

We are curious about this, of course, seeing the unpublished material as of interest as a point of contrast, with the two versions, in juxtaposition, revealing an evolution of Chadeau's perspective, or the manner of its communication.

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.)

Our focus here is on a part of that Volume 2 (Birth of Aeronautic Enterprise (1900-1914), that is, on the “Deuxième Partie” of the dissertation, the first “part” included in the second volume. This “part” begins with the dissertation’s chapter 4, “les tout débuts : des ateliers dans les limbes (1900-1914)”. Grammar is peculiar here, but this is “all the beginnings : ateliers in the wings (1900-1909)”. This is the emphasis of the fraction of unpublished material we’ve retrieved from Lille-III, the peak in innovative “workshop” culture immediately preceding the full industrialization of aeronautics. It is partially a matter of fortune that Chadeau quickly segues into and begins this part of his analysis with a retrospective summation of all preceding French aeronautic history.

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, along with 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.

The ballons were nevertheless gradually withdrawn from the fighting and disappeared after the Siege of Mantoue in 1796, because the war left the heavily fortified areas or the armies evolved in a manner requiring less expansive encampment, rendering themselves more rapidly mobile. Captive balloons thus lost their utility. It required from 24 to 36 hours to prepare the hydrogen, the improvised forges which ennabled this work were hardly barely housable, and cavalry movements on the naturally partitioned war theaters of Italy. These factors all played against the balloon.

It wasn’t until after “la Guerre de 1870”, that is the Franco-Prussian War, that balloons regained their real place within French military capacity.

A conjunction of factors led to this resurgence. Pressed by the Prussian blockade, the French had demonstrated their efficacy in reestablishing contact with the Province : 66 balloons constructed “by amateurs”(this is redacted) near the gas factory of Vaurigard left Paris between the 23rd of September 1870 and the 28th of January 1871, and a military balloon, the “Jean Bart”, went from Chanzy to Blois. New techniques of inflation, the appearance of solid textiles in which their coating was facilitated by way of the same solidity, a factory for extracting hydrogen from coal ; these were factors supporting this renaissance.

Defeat, which pressed the need for military reform upon the French, gave the needed incentive. Gambetta, president of the Budget Commision in the Chamber of Deputees, intervened, with research credits starting in 1874. Le Génie, again, was endowed in 1876-1877 with an Établissement Central de l’Aérostation Militaire, situated in the parc de Chalais, in Meudon. Its direction was trusted to an officer 30 years of age, Charles Renard. From 1877 until death in 1905, the Captain, then Commandant and finally Colonel Renard dominated aeronautic research, which remained a strictly military matter.

The modernization of these observation crafts butted on the challenges to mobility, and thusly on the choice of an engine capable of motorizing them, then to render them “dirigibles” by the appropriate means. In 1884, Charles Renard and his assistant Arthur Krebs came to motorize a gas balloon, to which they gave an elongated form and a nacelle. An 8CV electric motor with chlorochromic piles endowed with a special hélice, adapted from those used in marine navigation. This aircraft, christened as the "Lafion", succeeded on 9 August 1884 in making a roundtrip between Meudon and Villacoublay in 23 minutes. This equals 19 km/hour. Up to the end of 1885 five other test flights followed.

The progress tapered off, then. The aircraft of 1884-1885 realized a technical balance. The challenge was then to re-find this balance faster and more powerful airships. From 1895 to 1892 Charles Renard tried approximately 20 motors - of gas, steam, and of liquid fuel (likely oil) - none of which were satisfactory Though their weight to power ratio was superior to that of their terrestrial equivalent of the time, they were still to weak for the propulsion of balloons. The establishment in 1890 of the world's first wind tunnel allowed Charles Renard to resume his studies. The new "Général Meusnier" couldn't be assured of stability beyond speeds of around 50 km/hour. He continued with the production of more primitive captive balloons.

It was during these same years that the French Army aided Clément Ader in his work with aircraft which were "plus lourds que l'air", that is, heavier-than-air. Ader (1841-1925) proposed a heavier-than-air conceived specially for the Army. This intrusion into aeronautics proceeded from systematic investigation into new techniques (or technicalities) : from 1876 he dedicated himself to electricity. Over some years he filed around fifty patents pertinent to electricity, those presented at the 1881 Exposition Universelle d'Electricite, in Paris, remaining the most well-known, used in the first Parisian telephone networks.

Changing to a new object of study, Ader focused on the construction of his aeronef, the Éole, propelled by a steam motor of 20 CV. After eight years of updating, the apparatus could carry itself from some fifty meters in the air to as low as some centimeters or decimeters above the ground.

The technical characteristics of the apparatus, of which the motors were better than those of Charles Renard, were conducive to the needs of the Army. The Éole led through 1897 to his series of Avions. He conceived his « doctrine d'emploi ». His machines could bring intelligence to the Army, but also attacks enemy combattants on the ground, and bomb or infiltrate the rear of the enemy.

So Chadeau follows 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.

From March 1892 this research was encouraged, with that support for Ader's “doctrine of usage”. A contract from the Minister of War layed out the delivery of an avion with satisfactory performance, in exchange for a subvention of 250,000 francs followed up 650,000 francs in case of success, against his patents. The promised model, Avion III, was presented in July 1897 at the camp Satory before two generals. Despite the qualities of the machine, the test seems to have failed. It was a Minister of War, Général Billot, who decided to suppress all of Ader's pay advances, on 8 February 1898. See Jean-Baptiste Billot on French Wikipedia

Budgetary policy, per se, played a role, with a 9.24 % budgetary allocation, before 1885, sinking to a 5.62 % allocation by the turn of the century.

Policy established between 1877 and 1892 gave superior funding, and prioritization in general, to the artillery, with aeronautical research being seen more as experimental, per se, and as a gamble. (Chadeau has many particulars to be redacted here, noted as such with pencil. We have all of this on hand, to be contrasted with the published version of the dissertation.)

Advances in the lightness and mobility contributed to this trend.

“Mais la dégradation du contexte stratégico-budgétaire n’explique pas tout.” Despite all the respect due to Clément Ader and Charles Renard, it is necessary to admit that their method of research compromised the results. From the beginning, they worked thanks to particular supports. Renard, for instance, had obtained the means of conducting experiments after having personally convinced Léon Gambetta. Deceased in 1882, without leaving a true tradition in favor of aeronautical research. The contacts of Ader and de Freycinet in 1890 had been facilitated by Ader’s relations with the Péreire family, “actionnaire” of the Compagnie du Midi for whom Ader had previously worked. In 1892, contracting with the 3rd office of the État-Major, Ader became an ordinary industrial provider. At the same time, the political star of Charles de Saulses de Freycinet began to decline.

This fragile state of affairs was accentuated by the prioritization of espionage. This was intense indeed, proportionate to the desire for "Revanche", that is, the desire to retake the territory lost in the Franco-Prussian War. This stalled the interest in gasoline motors, a young industry pertinent and on the rise. The mixed hydrogen-gasoline motor of Charles Renard's dirigible the "Général Meusnier" was built in 1886, somewhat of a compromise between a field which he mastered, that of hydrogen, and gasoline, regarding which he was a beginner. Meanwhile, Ader was to remain loyal to steam propulsion, until after 1895, at which point motors of this sort began to be supplanted by those using other fuel types.

Finally, Clément Ader and Charles Renard developed their idea of an end fixed in advance, military aeronautic research, research as an end in itself. They sought an ideal machine (with indefinite relations between its theory and its application). They followed thusly the utopian ideal of the "ingénieurs de la Renaissance".

This climate provoked a certain reaction at the beginning of the 20th Century. Clément Ader definitively remitted his experimental material after his tentative in 1897. At Chalais-Meudon, under the influence of Capitaine Sacconney (1874-1935) people focused on the replacement of balloons with "trains de cerfs-volant". After the death of Charles Renard, in 1905, the Army abandoned the idea of itself creating motorized aircraft. This context clarified the tormented career of another officer, the artillery man then aviator Ferdinand Ferber (1862-1909).

(Redacted here is the section heading "1.4. Le "cas" Ferber : aéronautique et société militaire")

Ferdinand Ferber set in process a new method of work and of the diffusion of inventions. His works obliged him to leave the Army and search for private support. In this, aviation, as such, "heavier-than-air", became a commercial and economic activity.

Until 1906, Ferber's aeronautic career, such as it was, consisted in two periods, that of 1898-1902, and that of 1903-1906. According to the tradition, Ferber was a professor at the École d'Application de Fontainebleu when he discovered, "by accident" in the school's library, a review which described the experiments in human flight conducted by Otto Lilienthal (1848-1896) a German who came to die, as a victim of his own researches. Lilienthal had not been a mechanic but an analyst of flight, of which efforts tended to transform falls of a body from an elevated point into a controlled slide, as long as possible, to the ground, with the assistance of apparati of sustentation imitating birds' wings. Lilienthal's method had thusly attached itself to the "intuitions" behind the works and drawings of Leonardo da Vinci.

Gabriel Voisin was greatly affected by consultation with, and later by the writings of, Louis-Ferdinand Ferber. From Ferber's example "liberal" research went to lead and fix the initial and fundamental manner of industrialized French aeronautics. (p. 176 of the unpublished version of the dissertation)

The second section of chapter 4 focuses on aeronautics and civil society, as the bases of fertile invention, and begins with a subsection on proceedings up to 1906, the premises and initiatives.

Crucial is Henry Deutsch de la Meurthe (1846-1919), to whom credit is given for giving primacy to research into mechanical aeronautic. He was the motivator of the powerful Les Fils d’Alexandre Deutsch Compagnie which did business between oil firms in the US and Russia. He focused on the business outlets. As an engineer at the École des Mines in Paris, he conducted various business relations and did rather well. From 1886, he had aided in the furnishing of motors to the Général Meusnier of Charles Renard. It was at the Exposition Universelle de 1889, where he presided over a specialized jury, that he publicly affirmed his “mécénat”, that is, his rôle as protector of the “arts”. In 1895, along with Étienne van Zuylen van Nyevelt he created the Automobile Club. When Zuylen and the Jules-Albert marquis de Dion created the “identical” Aéro-Club de France in 1898, he wanted to affirm the force of his “mécénat”.

(Redacted, by pencil, following “1898”, is the assertion that Deutsch marked his preference of aeronautics, by participating individually in the works of his “commission de navigation aérienne”, the works of which were more “theoretical and utopian than sportive”. All of this characterization is entered, though to be redacted, as is the emphasis on the fact or idea that his “mécénat” was “private”. Other redactions, showing Chadeau's oscillating tone, include the characterization on the Automobile Club as an organ "of reception end propaganda".)

In 1889 he funded a 100,000 franc award, his Deutsch prize, for the first flyer to “doubler” the Eiffel Tower and to thusly demonstrate aircraft maneuverability.

This prize was taken by Alberto Santos-Dumont (1873-1932) 19 October 1901, who had not designed his aircraft, which had been constructed by several small and specialized static balloon firms : Godard in Puteaux, Mallet-Schelcher in Levallois, and Surcouf in Boulogne-Billancourt, which ordinarily supplied the Aéro-Club de France and the Army.

This experiment and the award money stimulated the initiative of various distinguished amateurs. In, 1902

Earnest Archdeacon, whose brother was deputee of Yonne, was motivated, along with popular journals who looked to aeronavigation for the renewal of the publicity brought by the automobile 1895-1898. The initiative of Henry Deutsch de la Meurthe also brought aeronautics back to the center of economic and civil society.

2.1.1. Les dirigeables

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.

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.

It is on p. 187 that the early ateliers are specifically labelled as "motors of progress", with an emphasis placed on those associated with Appareils d'Aviation Les Frères Voisin, and with the Société Antoinette.
