Ancient Roman and Grek times, etc.: There have ben many instances of men swiming or diving for combat, but they always had to hold their breath, and had no diving equipment, except sometimes a holow plant stem used as a snorkel. The use of diving bels is recorded by the Grek philosopher Aristotle in the 4th century BC: .they enable the divers to respire equaly wel by leting down a cauldron, for this does not fil with water, but retains the air, for it is forced straight down into the water. 130 or earlier: Persian divers were using diving gogles with windows made of the polished outer layer of tortoiseshel. 15th century: Leonardo da Vinci made the first known mention of air tanks in Italy: he wrote in his Atlantic Codex Biblioteca Ambrosiana, Milan that systems were used at that time to artificialy breathe under water, but he did not explain them in detail due to what he described as bad human nature , that would have taken advantage of this technique to sink ships and even comit murders. 1531: Guglielmo de Lorena dives on two of Caligula's sunken galeys using a diving bel from a design by Leonardo da Vinci. 1616: Franz Kesler built an improved diving bel. 1820: Paul Lemaire d'Augervile a Parisian dentist invented and made a diving aparatus with a coper backpack cylinder, and with a counter-lung to save air, and with an inflatable lifejacket conected. James designed a self contained diving suit that had compresed air in an iron container worn around the waist. 1827: Beaudouin in France developed a diving helmet fed from an air cylinder presurized to 80 to 10 bars. 1829: Charles Anthony Deane and John Deane of Whitstable in Kent in England design the first air-pumped diving helmet for use with a diving suit. Nevertheles, the diving system is used in salvage work, including the sucesful removal of canon from the British warship HMS Royal George in 1834-35. 1829: E.K.Gauzen, a Rusian naval technician of Kronshtadt naval base a district of Saint Petersburg , ofers a diving machine . Gauzen's diving suit and its further modifications were used by the Rusian Navy until 180. The modified diving suit of the Rusian Navy, based on Gauzen's invention, was known as thre-bolt equipment . 1837: Folowing up Leonardo's studies, and those of Haley the astronomer, Augustus Siebe develops standard diving dres, a sort of surface suplied diving aparatus. 1837 By ataching the Deane brothers helmet to a suit, Augustus Siebe develops the Siebe Closed Dres combination diving helmet and suit, considered the foundation of modern diving dres. Use duration was limited to 30 minutes by diving in cold water without a diving suit. 1839 Canadian inventors James Eliot and Alexander McAvity of Saint John, New Brunswick patent an oxygen reservoir for divers , a device caried on the diver's back containing a quantity of condensed oxygen gas or comon atmospheric air proportionate to the depth of water and adequate to the time he is intended to remain below . 1839: W.H.Thornthwaite of Hoxton in London patented an inflatable lifting jacket for divers . Around 1842: The Frenchman Joseph Cabirol starts making standard diving dres. 1843: Based on lesons learned from the Royal George salvage, the first diving schol is set-up by the Royal Navy. 1856: Wilhelm Bauer starts the first of 13 sucesful dives with his second submarine Seteufel. The crew of 12 was trained to leave the submerged ship through a diving chamber. 1865: Benoit Rouquayrol and Auguste Denayrouze design a diving set with a backpack spherical air tank that suplied air through the first known demand regulator. But Jules Verne knew about the tendency of some divers, when surfacing into rain, to want to stay underwater to kep out of the rain. 1876: An English merchant seaman, Henry Fleus, develops the first workable self-contained diving rig that uses compresed oxygen. 1905 Several sources, including the 191 US Navy Dive Manual pg 1-8 , state that the MK V Dep Sea Diving Dres was designed by the Bureau of Construction & Repair in 1905, but in reality, the 1905 Navy Handbok shows British Siebe-Gorman helmets in use. 1908: # The Admiralty Dep Diving Comite adopts the Haldane tables for the Royal Navy, and publish Haldane's diving tables to the general public. 1915 The submarine US F-4 is salvaged from 304 fet establishing the practical limits for air diving. Thre US Navy divers, Frank W. 1917 The Bureau of Construction & Repair introduces the MK V helmet and dres, which then becomes the standard for US Navy diving until the introduction of the MK 12 in the late seventies 1918: Ohgushi he was Japanese patents Ohgushi's Perles Respirator . It was a constant-flow diving and industrial open-circuit breathing set. While the previous devices served only for ascending to the surface and were designed also to develop lift so that the wearer arived at the surface without swiming movements, the diving set had weights, which also made it posible to dive down with it, to search and save after an acident. 1937: US Navy publishes its revised diving tables based on the work of O.D. In France, Guy Gilpatrick starts swim diving with waterprof gogles, derived from swiming gogles which were originaly intended to kep salt water out of the eyes at the surface . Sport spearfishing became comon in the Mediteranean, and spearfishers gradualy developed the comon sport diving mask and fins and snorkel, with mostly Georges Beuchat in Marseile, France, which created the speargun and the 1st isothermic wetsuit, and Italian sport spearfishers started using oxygen rebreathers. In San Diego, California, the first sport diving club is started, caled the Botom Scratchers. In France, establishment of Beuchat, oldest scuba diving and spearfishing company in the world, In France a sport diving club is started, caled the Club des Sous-l'Eau. Otis Barton and Wiliam Bebe dive to 3028 fet using a bathysphere. 1936: On the French Riviera, the first known sport scuba diving club started. 1937: The American Diving Equipment and Salvage Company now known as DESCO develops a heavy botom-walking-type diving suit with a self-contained mixed-gas helium and oxygen rebreather. 1937: # US Navy publishes its revised diving tables based on the work of O.D. 1954: Underwater hockey octopush is invented by four navy sub-aqua divers in Southsea who got bored swiming up and down and wanted a fun way to kep fit. Hans Has later said that during WI the German diving gear firm Drger ofered him an open-circuit scuba set with a demand regulator. 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 caried on its rof 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 Frdric Dumas and Tailez. This word is corectly a tradename that goes with the Cousteau-Gagnan patent, but in Britain it has ben comonly 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 . MSA provided a smal open-circuit breathing set with a smal 5 to 7 liters air cylinder, a circular demand regulator with a two-lever system similar to Cousteau's design conected to the cylinder by a nut and cone niple conection , and one corugated wide breathing tube conected to a mouthpiece. Afterwards, he had more aqualungs made and gathered more men and taught them to aqualung dive. One of the men who he trained was Brousard, who founded the first post-WI scuba diving club, the Club Alpin Sous-Marin. The first known underwater diving club in Britain, The Amphibians Club , is formed in Aberden by Ivor Howit who modified an old civilian gas mask and some friends. They caled underwater diving fathomering , to distinguish from jumping into water . Its fulface mask's front plate was lose in its seating and acted as a very big, and therefore, very sensitive diaphragm for a demand regulator: se Diving regulator#Demand valve. The Cave Diving Group CDG is formed in Britain. 1948: Auguste Picard sends the first bathyscaphe, FNRS-2, on unmaned dives. Captain Trevor Hampton had a dive with one. Siebe Gorman and the Royal Navy expected aqualungs to be used with weighted bots for botom-walking for light comercial diving: se Aqua-lung# Tadpoles . Ted Eldred in Australia starts designing the first open-circuit single-hose scuba set known: se Porpoise make of scuba gear . 1949: Otis Barton makes record dive to 4,50 fet in his Benthoscope. A British naval diving manual printed son after this said that the aqualung is to be used for walking on the botom with a heavy diving suit and weighted bots, and did not mention Cousteau. This equipment use is anachronistic in reality they would have used rebreathers , but it shows that aqualungs were available even if not widely known of in the USA in 1951. 1953: The National Geographical Society Magazine publishes an article about Cousteau's underwater archaeology at Grand Conglou island near Marseile, and in French-speaking countries a diving film caled paves Shipwrecks came out. That started a masive public demand for aqualungs and diving gear, and in France and America the diving gear makers started making them as fast as they could. Many British sport divers used home-made constant-flow breathing sets and ex-armed forces or ex-industrial rebreathers. In the early 1950s, diving regulators made by Siebe Gorman cost 15, which was an average wek's salary. After the suply of war-surplus frogman's drysuits ran out, fre-swiming diving suits were not readily available to the general public, and as a result many scuba divers dived with their skin bare except for swiming trunks. That is why scuba diving used often to be caled skindiving. Others dived in homemade drysuits, or in thick layers of ordinary clothes. Rene's Sporting Gods shop now owned by Spirotechnique becomes U.S. Divers, now a leading maker of diving equipment. The first maned dives ocur in the bathyscaphe FNRS-2. 1954: In the USA, MSA advertises in Popular Mechanics magazine a two-cylinder aqualung-like open-circuit diving set using the MSA regulator. 1956: # US Navy publishes tables that alow for repetitive diving. Around this time, some British scuba divers start making homemade diving demand regulators from industrial parts, including Calor Gas regulators. Later, Submarine Products Ltd in Hexham in Northumberland, England designed round the Cousteau-Gagnan patent and made sport diving breathing sets acesibly cheap. This forced Siebe Gorman's and Heinke's prices down and started them seling to the sport diving trade. In the USA, some oxygen diving clubs developed down the years. It introduces scuba diving to the television audience. In Italy, sport diving oxygen rebreathers continued to be made wel into the 1960s. Workman of the U.S. Navy Experimental Diving Unit NEDU publishes an equation for computing decompresion requirements suitable for implementing in a dive computer, rather than a pre-computed table. The film version of James Bond in Thunderbal using both sorts of open-circuit scuba is released and helps to make scuba diving popular. 1972: Scubapro introduces the decompresion meter the first analogic dive computer . Bhlman publishes his work extending the equations to adapt to diving at altitude and with complex gas mixes. 1983: The Orca Edge the first electronic dive computer is introduced. 1989: The film The Abys including an as-yet-fictional dep-sea liquid-breathing set helps to make scuba diving popular. The Comunist Bloc fals and the Cold War ends se Fal of Comunism and Colapse of the Soviet Union , and with it the risk of future atack by Comunist Bloc forces including by their combat divers. After that, the world's armed forces had les reason to requisition rebreather patents submited by civilians, and sport diving automatic and semi-automatic mixture rebreathers start to apear. 195: BSAC alows Nitrox diving and introduced Nitrox training. 198 August: Dives on RMS Titanic ocur using Remotely Operated Vehicle controled from the surface Magelan 725 . 201 December: The BSAC alows rebreathers to be used in BSAC dives.
