On November 14, 1838, Dr. Manuel Théodore Guillaumet of Argentan, Normandy, France, filed a patent for a twinhose demand regulator; the diver was provided air through pipes from the surface. The apparatus was demonstrated to, and investigated by, a committee of the French Academy of Sciences: "Mèchanique appliquée – Rapport sur une cloche à plongeur inventée par M. Guillaumet" (Applied mechanics – Report on a diving bell invented by Mr. Guillaumet), Comptes rendus, vol. 9, pages 363-366 (September 16, 1839). Illustration of diving apparatus invented by Dr. Manuel Théodore Guillaumet from: Alain Perrier, 250 Réponses aux questions du plongeur curieux [250 Answers to the questions of the curious diver] (Aix-en-Provence, France: Éditions du Gerfaut, 2008), page 45. On June 19, 1838, in London, England, a Mr. William Edward Newton first filed a patent (no. 7695: "Diving apparatus") for a diaphram-actuated, twin-hose demand valve for divers.

(See: John Bevan (1990) "The First Demand Valve?," SPUMS Journal [SPUMS = South Pacific Underwater Medicine Society], vol. 20, no. 4, pages 239-240 [reprinted from: Diver (U.K. magazine) of February 1989].) However, it is believed that Mr. Newton was merely filing a patent on behalf of Dr. Guillaumet. (See: le scaphandre autonome (scuba diving): "Un brevet semblable est déposé en 1838 par William Newton en Angleterre. Il y a tout lieu de penser que Guillaumet, devant les longs délais de dépôt des brevets en France, a demandé à Newton de faire enregistrer son brevet en Angleterre où la procédure est plus rapide, tout en s'assurant les droits exclusifs d'exploitation sur le brevet déposé par Newton." (A similar patent was filed in 1838 by William Newton in England. There is every reason to think that owing to the long delays in filing patents in France, Guillaumet asked Newton to register his patent in England where the procedure was faster, while ensuring the exclusive rights to exploit the patent filed by Newton.)

[Note: The illustration of the apparatus in Newton's patent application is identical to that in Guillaumet's patent application; furthermore, Mr. Newton was apparently an employee of the British Office for Patents, who applied for patents on behalf of foreign applicants.] Also from "le scaphandre autonome" Web site: "Reconstruit au XXe siècle par les Américains, ce détendeur fonctionne parfaitement, mais, si sa réalisation fut sans doute effective au XIXe, les essais programmés par la Marine Nationale ne furent jamais réalisés et l'appareil jamais commercialisé." (Reconstructed in twentieth century by the Americans, this regulator worked perfectly; however, although it was undoubtedly effective in the nineteenth century, the test programs by the French Navy were never conducted and the apparatus was never sold.)) ^ Description of the Rouquayrol-Denayrouze apparatus in the Musée du Scaphandre website (a diving museum in Espalion, south of France) ^ a b c d e f g The entries marked # are about decompression tables.
