Scuba diver of the late 1960s. The history of scuba diving is closely linked with the history of the equipment.By the turn of the twentieth century, two basic architectures for underwater breathing apparatus had been pioneered; open-circuit surface supplied equipment where the diver's exhaled gas is vented directly into the water, and closed-circuit breathing apparatus where the diver's carbon ...
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.
The first commercially practical closed-circuit scuba was designed and built by the diving engineer Henry Fleuss in 1878, while working for Siebe Gorman in London. [ 14 ] [ 73 ] His apparatus consisted of a rubber mask connected by a tube to a bag, with (estimated) 50–60% O 2 supplied from a copper pressure tank and CO 2 chemically absorbed ...
Émile Gagnan. Émile Gagnan (1900 – 1984) was a French engineer and, in 1943, co-inventor with French Navy diver Jacques-Yves Cousteau of the Aqua-Lung, the diving regulator (a.k.a. demand-valve) used for the first Scuba equipment. [1]
The invention revolutionised autonomous underwater diving by providing a compact, reliable system capable of a greater depth range and endurance than its precursors, and was a major factor influencing the development of recreational scuba diving after WWII. The twin-hose Aqua-Lung demand regulator is the foundation of all modern scuba regulators.
Yves Le Prieur – French naval officer and inventor of a free-flow scuba system (1885-1963) John Lethbridge – English wool merchant who invented a diving machine in 1715 (1675-1759) Diving suit William Hogarth Main – Cave diver and scuba configuration experimentalist "Hogarthian" rig
The first diving club was created in France in 1935 by le Prieur and Jean Painleve, it was called the "club des scaphandres et de la vie sous l'eau", the club for divers and life under water. [5] [6] [7] In 1946, Le Prieur invented a further improvement to his scuba set.
Draeger twin hose two stage demand regulator. The most striking and well recognized example of vintage scuba gear is the twin-hose or double hose regulator, a popular style of regulator in the early years of scuba diving, since Jacques-Yves Cousteau and Emile Gagnan pioneered the first such design, the C45 Scaphandre Autonome, which was marketed in the USA (along with a tank and harness) as ...
