  2. Black, 1943, pp. 30–31. "The first successful glide is believed to have been made in France by a sea captain by the name of Le Bris. The report of this glide originally came out through the publication of a novel of the period; hence doubt arose regarding its authenticity. Octave Chanute, who made an investigation of the report, became convinced, however, that the novelist had based this part of his story upon the actual happening. Le Bris is supposed to have studied the flights of the albatross on the French coast and decided to construct a glider patterned after one of these large birds. This he evidently did, and from all accounts it must have been a fearful and wonderful device. Yet the apparently authenticated reports say that Le Bris actually did make a glide about an eighth of a mile on a main road near Douarnenez in about 1855. A man of small means, he had no funds to continue the work and after damaging a couple of gliders he was forced to give up his efforts. No extensive interest seems to have been taken in the work at that time, since this was the period when interest centered mainly upon the balloon."

(A peculiarity in this search is that "LE BRIS" segued to false leads, and "voiture aérienne", with the proper accent mark, led to nothing, whereas "voiture aerienne", sans accent, led to the proper material. With INPI, previously, the accent marks were necessary ; now they seem to be getting phased out, within search terms though not within actual content.) http://bases-brevets19e.inpi.fr/Thot/FrmFicheDoc.asp?idfiche=0145794&refFiche=0090870
