At first specializing in brass instruments, Pierre Louis Gautrot established his firm as "Gautrot aîné" ("elder") in 1845 as successor to Guichard. The oval cartouche with the letters "GA" shown above is a very early trade mark. He later adopted one that incorporated an achor as his mark. (See another Gautrot horn in this collection.) By 1846 Gautrot claimed to be the most important factory of its kind in Europe, with a workforce of over 200, with 3,000 cornets, 1,000 trombones, and 1,000 ophicleides. On August 6, 1847 Gautrot along with Raoux, Halary, Buffet, and Gambaro, all of whom were normally competitors, filed suit against both of Sax's patents: that of 1843 ("Chromatic instrument system"), and that of 1845 ("A musical instrument, called the saxotromba"). (The complaint of the instrument manufacturers was based on the claim that Sax's improvements had long been known at home and abroad. The suit went through five appeals and ended in 1854 with a victory for Sax.) The loss of the potential military band market was perhaps one of the reasons for Gautrot's antagonism toward Sax. By 1847 he had a workforce of 208, comprising 42 percent of the entire brass instrument workforce of Paris. This was the period of the manufacture of the horn described here.
Describing developments on the manufacture of musical instruments for the year 1847, Adolphe Le Doulcet Pontécoulant wrote:
Gautrot, apporta quelques perfectionnements dans la construction des instruments de musique en cuivre. Le but des recherches de Gautrot paraît avoir été de réformer les tons de rechange des instruments en cuivre qui sont susceptibles de changer de ton, et il croit y être parvenu par l'application de trois cylindres transpositeurs faisant exactement l'office de robinets employés dans diverses industries. Le facteur a adapté une disposition particulière des cylindres et des robinets mis en rapport de tons avec les coulisses et il n'emploie qu'une seule coulisse mobile. Le facteur peut changer dix fois de tons sans être obligé d'accorder les tons sur les cylindres. (B. F., 5,874.)
[Organographie: essai sur la facture instrumentale, art, industrie et commerce, Tome 2, p.453]

[Gautrot brought some improvements in the construction of brass musical instruments. The goal of Gautrot's research seems to have been to reform the crooks of brass instruments which are susceptible to changing tonality, and he believes it to be achieved by the application of three transposing cylinders acting exactly as taps employed in various industries. The builder has adapted a particular arrangement of cylinders and taps connected to crooks with slides and he employs only one mobile slide. The builder can change tonality ten times without having to adjust the crooks on the cylinders. (French patent, 5,874.)]
[Note: The New Langwill Index (p.130) cites the patent as "1847 (F) #3170: improvements to horn ('cor omnitonic')". This is believed to be Gautrot's first patent award.]

Reginald Morley-Pegge describes this horn as follows:
Several clever versions of the omnitonic horn were patented by P.-L. Gautrot, whose pioneer work in the improvement of brass instruments has been rather lost sight of in the blaze of publicity and official patronage that surrounded every word and deed of his contemporary Adolphe Sax. Many of his inventions were extremely ingenious, even if they were not always practical. His first omnitonic horn, patented in 1847, had three rotary quick-change taps and a double tuning slide. It possessed the advantage over previous horns of this type of allowing for as many as twelve crook changes, namely B-flat, A, A-flat, G, F, E, E-flat, D, D-flat, C, B-flat basso, and A Basso. The complicated adjustments of slides and taps required to switch from one tonality to another seem, at any rate on paper, to be quite as lengthy a process as changing an ordinary crook, and this, together with what, for a hand horn, must have been excessive weight, no doubt accounts for the fact that it attracted little notice in professional circles.
[The French Horn, p.58f.]

 

 

 

The tonality of the horn is controlled by three taps and a long main slide. The top of each tap (above left) is marked with "O" (Ouvert "open") and "F" (Fermé "closed") indating which way to turn the wing nut attached to the rotor inside the cannister. The bottom of the tap (shown above center with the bottom cap removed) has a pin constrained by a 90° arc slot to limit the rotation of the tap. The long central slide is supported by a pair of guides (above, left) and may be extended to further affect the tonality. Also each segment controlled by the taps has its own slide for fine tuning. The table below shows the length of tubing controlled by each tap and the possible combinations with the resulting tonalities. (Note: the taps are numbered in the order they are encountered in the airway and not in the positions corresponding to the valved horn. That is, the center tap is 1, the top tap (nearest the mouthpiece) is 2, and the bottom tap is 3.)

Note: the above table is theoretical only. The specimen horn is currently not functional since all three taps and main slide are frozen. The tonalities have been calculated by comparison of the aggregate lengths with a contemporary cor d'orchestre with an original set of crooks. The additional tonalities missing in the table but cited by Morley-Pegge (e.g. A-flat) can probably be obtained by extending the main slide.

A mysterious mark or insignia is stamped on the leadpipe.

The horn bears the coat of arms of Louis-Philippe, "The King of the French." As a result of the "July Revolution" of 1830 France had become a constitutional monarchy and Louis-Philippe, Duc d'Orléans was crowned the new king. At first he used the arms of Orléans surmounted with a coronet of the monarchy to be his coat of arms. The following year the arms were officially changed to those shown here and were the Arms of France until Louis-Phillipe's abdication on February 24, 1848. This would seem to pinpoint the date of manufacture of this horn to within a single year since it was patented only the year prior to the dissolution of the monarchy and the disuse of these arms.

The portrait and frame were sent in 1848 to King Kamehameha III of Hawaii and have stayed there since.

The Ordonnance of Feb. 26, 1831 reads: À l'avenir, le sceau de l'État représentera un livre ouvert portant à l'intérieur ces mots "Charte de 1830", surmonté d'une couronne fermée, avec le sceptre et la main de justice en sautoir, et des drapeaux tricolores derrière l'écusson, et pour exergue "Louis-Philippe Ier, Roi des Français". That is, an open book with the words "Charter of 1830", (the shield) surmounted by a closed crown; behind the shield, in saltire, were the scepter and hand of justice, as well as tricolor flags. King Louis-Philippe abdicated the throne but the strong current of public opinion rejected the nomination of his son, Phiippe, as the new monarch. On February 26, the Second Republic was proclaimed and Prince Louis Napoleon Bonaparte was elected President in December. A few years later he declared himself president for life and then Emperor Napoleon III. This image is a file from the Wikipedia Commons.
<<>>Musical Politics in France<<>>
On April 22, 1845 a public comparison of bands was held on the Champs-de-Mars: one assembled by Adolphe Sax versus one assembled by Michele Enrico Carafa, director of the Gymnase de Musique Militaire where most musicians of the army were trained. Reportedly, over 20,000 spectators were present to witness the contest between Sax, who wanted to reorganize the military bands to incorporate his line of saxhorns, and Carafa, who advocated retaining the traditional instrumention including natural horns. Sax was the clear victor and the new order that came in 1846 specified four cors à pistons and no natural horns, as well as a full complement of saxhorns. Although the omnitonic horn patent was issued in 1847, it was probably in development much earlier while natural horns were still in the military band complement. It would seem likely that this was Gautrot's target market. The order of 1846 eliminating natural horns along with the apparent disinterest on the part of the faculty of the Conservatiore and orchestral musicians, the market for the omnitonic horn all but disappeared.

On February 24, 1848, under public pressure Louis-Philippe suddenly abdicated the throne of France in what became known as the Revolution of 1848. That also became a very difficult year for music, musicians, and instrument manufacture in France:
Les fabricants d'instruments de cuivre, qui en 1847 avaient vu le chiffre de leurs affaires commerciales s'élever à 1,620,500 fr. et qui occupaient, à Paris seulement, 461 ouvriers, virent ces mêmes affaires se réduire 923,500 francs et furent obligés de renvoyer 102 ouvriers.
[Pontcoulant,Organographie, Tome 2, p.468]

Manufacturers of brass instruments, which in 1847 had seen the total of their business reach 1,620,500 fr. and had occupied in Paris alone 461 workers, saw these same figures reduced to 923,500 francs and were forced to dismiss 102 workers.

The general depression affected all instrument manufacturers in a similar manner. The Opéra-National and lyric theatres were forced to close, musicians and singers were put out of work, and the "cloud of concerts" that usually took place in Paris disappeared.

Immediately following the fall of the monarchy, Carafa sought his revenge on his defeat by Sax in 1845-6. He persuaded the Ministry of War to reverse the order of 1846. As a result the order of March 21, 1848 reinstated the two cors ordinaires (natural horns) and the saxhorns were replaced with traditional instruments much to the dismay of the musical press who perceived this a huge step backward. This would seem to have been favorable for Gautrot's omnitonic horn which is essentially a natural horn without the cumbersome box full of terminal crooks.

<<>>A Franco-Mexican Connection<<>>


An inscription on the bell identifies "I. Charpentier à Mexico" (perhaps a sales representative for Gautrot or horn player).


As cited previously, Gautrot held thousands of instruments in stock in 1847, which undoubtedly included some quantity that were already stamped with the arms of the monarchy and were thus no longer marketable in France. This circumstance, along with the generally depressed state of the music business in France in 1848, compelled Gautrot to put this instrument out for export. He was probably already seeking to develop his export market which by 1860 was reported to be 70 percent of his output. Presumably M. I. Charpentier was Gautrot's representative in Mexico. The war between Mexico and the United States was just ending; the Peace treaty was signed on February 2, 1848, almost simultaneously with the fall of the French monarchy. Nancy Nichols Barker summarizes France's relationship with Mexico under Louis-Philippe as follows:
The Orleanist government simply had no Mexican policy in the decade of the 1840s. The government had just sense enough not to repeat the naval action of 1838-39 but found nothing to take its place. Conscious of its ineffectiveness, it sulked and snapped, and, while professing officially its desire to live on good terms with Mexico, maintained representatives in the field with manifestly hostile intentions. Objects of ridicule and scorn, these agents hindered, instead of helping, the interests they were there to serve. French subjects in Mexico were left to their own devices to cope with the civil wars and Francophobe administrations. French commerce never recovered from the blows dealt it by the French war of the previous decade and by 1847, when Mexico was under the American blockade, it all but ceased entirely.

It was of course true that many of the elements necessary for the prosperity of the French in Mexico were beyond the control of the French government. Nevertheless, the policy of laissez-faire, at least as practiced by the so-called bourgeois monarchy, proved more curse than blessing to its subjects and trade in Mexico. Its deplorable record might well serve to demonstrate to a more energetic and visionary French ruler the perils of aimless drift and the need for a bolder course.
The French Experience in Mexico 1821-1861, p. 116
Relations between France and Mexico improved almost immediately following the fall of the French monarchy. André Nicolas Levasseur was appointed the new minister plenipotentiary to Mexico. Soon trade was restored between the two countries and the Mexican army was rebuilding under the French model with the newest weapons, training, and perhaps even French musical instruments.
It would be improper, in speaking of the Mexican military, not to notice, especially, their excellent bands of music. ... It is the custom for one of the regimental bands to meet after sundown, under the windows of the Palace, in the Plaza, which is filled with an attentive crowd of eager listeners to the choicest airs of modern composers.
Mayer, Brantz. Mexico as it was and as it is, Third Edition. Philadelphia: G. B. ZIEBER & COMPANY, 1847. p. 287
Levasseur's first official assignment was to canvass the French community and produce a "register" of French citizens. In characterizing the French community in Mexico at mid-century, Barker states:
The French had become something like a small state within a state. They seem to have mixed very little in Mexican society except at the official level. The French minister formed social ties with prominent Mexicans, attended the opera, and received Mexican guests at the legation. But he was an exception. Those who could afford it, careful to preserve their national identity, sent their children to French-speaking schools and subscribed to French newspapers. The working classes kept much to themselves, spending their days in their shops and their evenings or other free time at a café or in a game of boules. Not even to attend mass did the French need to mix with Mexicans, at least in the capital. In 1849 Levasseur reported the consecration of a church especially for French use. Beneath vaulted arches hung with the tricolore the French curé presided over their spiritual life and the more dignified, sober displays of French patriotism.

Why did the urban Frenchman in Mexico cling so tenaciously to his qualité de français and resist assimilation into Mexican society? One reason no doubt was the relatively short time he had had to learn the Spanish language or to adopt a Mexican life-style. For almost without exception the French in Mexico at mid-century were first generation. Only 3 in Levasseur's survey gave Mexico as their place of birth, and none of these can be proved to have been in Mexico as early as 1820. Only 12 had been born elsewhere in the Americas. Indeed, only 47 out of the entire 1,810 on Levasseur's list had been born outside the French métropole. The French were thus newcomers not only to Mexico but to the New World in general. The earlier French of the eighteenth century had departed, and a new generaton had replaced them.

<<>>Musical Life in Mexico<<>>

With both local and touring productions beginning around 1830, Italian opera enjoyed some popularity in Mexico. It was not without its ups and downs, however:
I have said, that this musical taste pervades all classes; and it was, therefore, to be hoped, that a regularly established Operatic corps would have readily succeeded in the Capital. But from a variety of causes the experiment failed. The Revolution of 1841, interfered with it at the outset, in the months of August and September; and, from the unfavorable location of the house, and other circumstances, the whole enterprise was visited with a series of disastrous losses that left the management, in July, 1842, with a deficit of upward of 32,000 dollars. The singers were good: the prima donna (Madame Castellan,) and basso, unexceptionable; but the establishment never became fashionable.
op. cit., Mayer, p. 287
By 1847 when this horn was made, however, the situation began to improve and the instrument might have been employed in the opera orchestra rather than the military band.


The History of North American Theater: The United States, Canada, and Mexico, p. 149


Of the several theatres in Mexico City at mid-century the two leading were the remodeled Teatro Principal (above) and El Gran Teatro Nacional (below) built in honor of Santa Anna in 1844. On May 15, 1850 the Teatro Nacional presented Verdi's "Ernani" to the Mexican public featuring la Compañía de Ópera Valtellina-Duvercy under the direction of Antonio Barilli. This was the first performance of a Verdi opera in Mexico. The following year, Max Maretzek presented "Don Giovanni" said to be the first performance of a work by Mozart in Mexico. Other Mexican venues include the Gran Teatro Iturbide (1845, later named Teatro de la República) in Santiago de Querétaro, and the Teatro Alarcón in Guadalajara which opened in 1856 with Donizetti's "Lucia di Lammermoor".



The History of North American Theater: The United States, Canada, and Mexico, p. 154


Brantz Mayer (Mexico as it was and as it is, p. 45) describes the Catte Platens in Mexico City as "a street filled with the shops of goldsmiths, watchmakers, French hairdressers, French cooks, French milliners, French carvers and gilders, and French print-sellers;". Apropos of the latter the amount of French books exported from France to Mexico in 1846 was close to 9,000 kgs, and "the figures for Mexico will grow to 26,284 kgs in 1849 and 37,586 kgs in 1850." By 1851 "Mexico received 44,327 kgs of French books, or more than Brazil (33,847 kgs) and only some 15,000 kgs under the figure for the United States. Book exports to Mexico decrease after that year, but remain high (e.g., 22,917 kgs in 1860, in the midst of the civil war)."

One other Gautrot instrument is found from Mexico. It is item number B178 in the Kenneth Fiske Museum collection and is described as: Flugelhorn in C, Pierre L. Gautrot, Paris, ca. 1880. Stamped: H. Nagel sucres Calle de la Palma No. 5, Mexico.

<<>>Later Gautrot Omnitonic Horns<<>>

In 1855 Gautrot introduced a new model of omnitonic horn. In the same breath as cited above for Gautrot's 1847 omnitonic horn, Pontcoulant mentions the Tonwechsel-Maschine patented by Cerveny on April 26, 1846. [See also Heyde, p.63f.] This is a multi-position tap used by several German manufacturers and also adopted by Gautrot for his improved omnitonic horn. The influential Belgian critic Franois-Joseph Fétis was not impressed and compared it unfavorably with the omnitonic horn developed much earlier by Charles-Joseph Sax:
Gautrot prsenta un cor-transpositeur. D'aprs M. Fétis qui a suivi et tudi les travaux de Sax père Bruxelles, ce nouveau cor-transpositeur n'tait qu'une imitation maladroite du Cor-omnitonique que Sax construisit en Belgique il y a prs de trente ans. (B. F., 22,538).
[Pontcoulant,Organographie, Tome 2, p.512]

[Gautrot presented a cor-transpositeur. According to Mr. Fétis who followed and studied the work of the elder Sax in Brussels this new cor-transpositeur was just a clumsy imitation of the Cor-omnitonique that Sax built in Belgium almost thirty years ago. (BF 22538).]
Of Gautrot's later models Morley-Pegge has this to say:
His last valveless omnitonic horn--probably the last instrument of this class ever made--appeared in the 1870s [sic, perhaps as early as 1855, see above]. It was made by M. Miramont, who died in 1935 after having been with the firm for sixty five years. This very odd, octopus-like instrument has a single central rotary tap from which radiate eight windways (Plate V, 5). Only six tonalities are available: B-flat alto, A-flat, G, F, E-flat, and D-flat, from which it is evident that this horn was intended for the wind band and not for the orchestra.
The French Horn, p.60.

This illustration also appears in the catalog of "Alliance Musicale", J.R. Lafleur & Son, London, estimated to date between 1891 and 1900 with the following dubious description:
"French Horn, without crooks. This Instrument, newly invented [sic!], has central rotary valves (see drawing), which after very little practice will be found of great benefit to the performer. By following the directions engraved on the these valves the instrument is put in any of the ordinary 10 keys as a French Horn with the 10 crooks, thereby saving the great trouble of carrying these 10 crooks about, with the risk of losing or breaking them in the hurry to change the crook. Without finger valves."
[Larigot, No. X Special, pp. 64-65 and Larigot, No. 36, p. 30]
