Where does the word scuba diving come from?

Answer 1

1839 Canadian inventors James Eliot and Alexander McAvity of Saint John, New Brunswick patent an "oxygen reservoir for divers", a device carried on the diver's back containing "a quantity of condensed oxygen gas or common atmospheric air proportionate to the depth of water and adequate to the time he is intended to remain below".[4] But was that Scuba (Self Contained Underwater Breathing Apparatus) or ORFD? sounds like SCUBA, but... there is another entry:
1876: An English merchant seaman, Henry Fleuss, develops the first workable self-contained diving rig that uses compressed oxygen. This prototype of closed-circuit scuba uses rope soaked in caustic potash to absorb carbon dioxide so the exhaled gas can be re-breathed. but most people generally agree that MODERN SCUBA was invented by a couple of guys in France: 1943: Jacques Cousteau and Emile Gagnan invent and make an open-circuit diving breathing set, using a demand regulator which Gagnan modified from a demand regulator used to let a petrol-driven car run on a big bag of coal-gas carried on its roof during wartime shortages of petrol. Cousteau had his first dives with it. He made two more aqualungs: there were now 3, one each for Cousteau and his first two diving companions Frédéric Dumas and Taillez. His aqualung remained a secret until the south of France was liberated. This type of breathing set was later named the "Aqua-Lung". This word is correctly a tradename that goes with the Cousteau-Gagnan patent, but in Britain it has been commonly used as a generic and spelt "aqualung" since at least the 1950s, including in the BSAC's publications and training manuals, and describing scuba diving as "aqualunging".

Answer 2

Diving, using trapped/contained ambient pressure air with no air-supply connection to the surface, likely began many centuries ago. With enough weight to counteract the buoyancy of the trapped air, almost anything is possible, and was probably attempted. Breath-hold or 'free' diving's origins, however, can be traced back to several thousand years BC, most likely attempts to salvage sunken treasure from wrecked ships. Both commercially and recreationally, free diving is still, by far, the most common and frequent. Cheapest, too. Strictly speaking, however, Self-Contained Underwater Breathing Apparatus, or SCUBA, using pressurized (150 atmospheres/approx 5300(!!!)lbs) air with a downstream user-demand regulator valve can be very closely dated. In his (highly reccomended) 1953 book, "The Silent World", Capitaine Jacques-Yves Cousteau describes how, in June, 1943, he first tested (his own design of) the world's first (23kg) 'aqualung', accompanied by Phillipe Taillez as (surface) dive-boat 'tender' and Frederic "Didi" Dumas as 'safety' (skin) chase diver. Capitaine Cousteau's wife, Simone was to observe only, using mask and schnorkle.

Answer 3

Ancient swimmers used cut hollow reeds to breathe air, the first rudimentary snorkel used to enhance our abilities underwater. Around 1300, Persian divers were making rudimentary eye goggles from the thinly sliced and polished shells of tortoises. By the 16th century, wooden barrels were used as primitive diving bells, and for the first time divers could travel underwater with more than one breath of air, but not much more than one.In 1771, British engineer, John Smeaton invented the air pump. A hose was connected between the air pump and the diving barrel, allowing air to be pumped to the diver. In 1772, Frenchmen, Sieur Freminet invented a rebreathing device that recycled the exhaled air from inside of the barrel, this was the first self-contained air device. Freminet's invention was a poor one, the inventor died from lack of oxygen after being in his own device for twenty minutes.In 1825, English inventor, William James designed another self-contained breather, a cylindrical iron "belt" attached to a copper helmet. The belt held about 450 psi of air, enough for a seven-minute dive. In 1876, Englishmen, Henry Fleuss invented a closed circuit, oxygen rebreather. His invention was originally intended to be used in the repair of an iron door of a flooded ship's chamber. Fleuss then decided to use his invention for a thirty-foot deep dive underwater. He died from the pure oxygen; oxygen is toxic to humans under pressure.In 1873, Benoît Rouquayrol and Auguste Denayrouze built a new piece of equipment a rigid diving suit with a safer air supply, however it weighed about 200 pounds.Emile Gagnan and Jacques Cousteau invented the modern demand regulator and an improved autonomous diving suit. In 1942, redesigned a car regulator and invented a demand regulator that would automatically fresh air when a diver breathed. A year later in 1943, Cousteau and Gagnan began selling the Aqua-Lung.
