The timeline of underwater diving technology is a chronological list of notable events in the history of the development of underwater diving equipment. With the partial exception of breath-hold diving, the development of underwater diving capacity, scope, and popularity, has been closely linked to available technology, and the physiological constraints of the underwater environment.

Primary constraints are

Pre-industrial

Industrial era

Start of modern diving

Rebreathers

Main article: Rebreather § History

Diving helmets improved and in common use

The first diving regulators

Diving set by Rouquayrol and Denayrouze with barrel-shaped air tank on the diver's back, depicted here in its surface-supplied configuration.

Gas and air cylinders appear

Underwater photography

Decompression sickness recognised as a problem

According to different sources, the term "The Bends" for decompression sickness was coined by workers of either the Brooklyn or the Eads bridge, and was given because afflicted individuals characteristically arched their backs in a manner similar to a then-fashionable posture known as the Grecian Bend.[63]

Twentieth century

The demand regulator reappears

World War II

Postwar

Public interest in scuba diving takes off

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.)
  53. ^ On 14 November 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 (16 September 1839).
  54. ^ 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.)
