J. Blanc  was a professor of music at the Collège de l'Arc, Dole, Jura, France.  He was the author of two méthodes  for horn: Nouvelle Méthode de Cor and Grande Méthode de Cor suive d'un Traité complet de Cor À Pistons. No dates are indicated on either of these publications, however the first has been dated to 1828 and the second to 1845 or before.

Monsieur J. Blanc is undoubtedly the same person as Jean Antoine Blanc born in Barcelona, Spain, January 21, 1793 and died at Lons-le-Saunier, Jura, France on December. 23, 1869.¹  He is now best known for his concert piece for organ La procession de la fête d'un village surprise par un orage, op 14. In the preface to the edition published by Delatour (2004), Pierre Guillot writes:

This work of Lédonien.² Jean-Antoine Blanc was first published in 1863 (and probably never since) by Romary Grosjean in his famous Journal des Organists. The great déodatien.³ publisher-organist published in the same journal a "Grand chœur pour sortie" by the same author. This, it seems, to all the musical works remaining of Jean Blanc - where are the thirteen opuses preceding this Procession? - should be add his opus 15, Méthode Spéciale pour L’étude des Pédales de l'Orgue, published by the Parisian publisher Richault in 1866, dedicated "to François Benoist, professor of organ at the Paris Conservatory, who kindly approves this work." But this Méthode does not seem to be preserved, despite the small reputation it earned its author through the celebrated organist Montauban Jean-Baptiste Labat who wrote its preface [1].

What remains of his reputation? Very little is known about Jean Blanc, tenured organist for the Cordeliers at Lons-le-Saunier (Jura) between 1837 and 1869, and the author of this Procession posted here. He was born in Barcelona, Spain, January 21, 1793. How has did he arrive at the birthplace of Rouget de Lisle? That is currently unknown. But he is there in the 1830s both as an organist and as a music teacher, a double position he held until his death at Lons-le-Saunier, December 23, 1869. Married to Marie Antoinette Majorai (born in Madrid and died in Lons February 18, 1865), they will have at least one daughter, Suzanne - later Mme. Louis Elisha Jeaux  - who was a music teacher like her father and shared a time, but fully, his tenure of church of the Cordeliers. Seemingly preoccupied with developing playing with pedals in France, Jean Blanc played an important role in changing the pedal organ sound at Cordeliers in Lons le Saunier in 1842. On the other hand and simultaneously, he attempted to establish a factory in his city for pedals adaptable to the upright piano.

[1] In his famous work L'orgue [...] (Nancy, Vagner, 1850) abbot Régnier had already raised the interest of Jean Blanc to the pedals of the organ.

4° Marche Funèbre, by Mohr.

J. Blanc's Nouvelle Méthode de Cor was published in Lyon by Cartoux in 1828. It is dedicated it to Étienne Gihot (1775 - 1833), from which it might be inferred that M. Blanc had studied with M. Gihot who was eighteen years his senior.

The frontispiece (below, right) is by Claude Barthélémy Pointurier (1789 - 1856). ⁵

J. Blanc's Méthode de Cor à Pistons and the Grande Méthode de Cor suive d'un Traité complet de Cor À Pistons 2 Edition were published by Alexander Grus, Paris in 1845 or earlier (see advertisement, top right).  The Grande Méthode is a reprinting of the original Nouvelle Méthode of 1828 described above with the Méthode de Cor à Pistons appended.
