Rebreather History: From Conception to the Modern Era (1680-2012)

By Michael Menduno

1680: Giovanni Borelli conceives the closed circuit rebreather. Believed recirculating air through copper tube cooled by seawater would allow impurities to condense.

1726: Stephan Hale developed a device for surviving mine disasters. The helmet contained a flannel liner soaked in sea salt and tartar as a scrubber (first chemical scrubber).

1773-4: Oxygen independently “discovered” in Sweden by Carl Wilhelm Scheele and in England by Joseph Priestley.

1776: Freminet designed a copper kettle diving helmet based on Borelli’s theory; concludes condensation does not remove impurities and installs a surface supplied line to the diver using a mechanical bellows to pump air.

1778: Antoine Lavoisier, a French nobleman and ‘Father of Modern Day Chemistry’, coined the name oxygen.

1878: Henry Fleuss and the Siebe Gorman company receive patent on recirculating device using pure O2. A year later he uses the device for the first enriched air nitrox dive. The practicality of the Fleuss system is demonstrated by repairing flooded tunnels two years later.

1878: Barometric Pressure is published by Dr. Paul Bert. The volume discusses oxygen toxicity, hypoxia and decompression sickness.

1881: Achilles, Khotinsky & Simon Lake receive patent for a rebreather that uses barium hydroxide as a chemical scrubber to remove CO2.

1904: Siebe Gorman receives patent for Oxylite, a potassium and sodium peroxide mix that liberates O2 on contact with water.

1905: A Fleuss apparatus is patented for use in submarine escape.

1908: Development of the first staged decompression techniques (Haldane).

1912: Draegerwerk demonstrates a submarine sled with a two-hour closed circuit supply of O2. Scientific American magazine predicts this development could be “the advent of a new sport.”

1915: Oxylite rebreathers are used for underwater scenes shot for movie Twenty Thousand Leagues Under the Sea.

1919: Patent for oxygen-helium breathing mixtures (C.J. Cooke)

1925: U.S. Bureau Of Mines experiments with helium decompressions (Hidebrand, Sayers, Yant).

1926: First self-contained open circuit SCUBA system (Fernez-Le Prieur)

1928: British air with oxygen decompression tables to 320 fsw (Davis, Damant).

1935: Nitrogen narcosis attributed to elevated nitrogen partial pressures (Behnke).

1937: First successful Heliox Dive to 420 fsw (End, Nohl).

1939: U.S. Navy (USN) Heliox Tables published (Behnke). Successful rescue and salvage operation of USS Squalus in 240 fsw.

1940-1944: Italians use O2 rebreathers against the British at Gibraltar. Brits counter with EAN rebreathers with mixtures of 32.5, 40 and 60 percent oxygen. The increased depth capacity of these mixes versus pure oxygen gives the British a distinct military advantage in their defense of Gibraltar. Use of these mixes is classified a state secret and was one of the well kept secrets of WWII. Lamerbertson develops the LARU, Lambertson Amphibious Respiratory Unit rebreather.

1942: Hans Haas completed the filming of his second underwater movie called Menschen unter Haien (i.e. Men Among Sharks), shot in the Aegean Sea and the Sea of Crete, and featured Haas in a Dräger rebreather.

1943: Development of the Gagnan-Cousteau ‘Aqualung’ demand valve regulator.

1943: Enriched air nitrox first proposed as a diving gas to reduce decompression problems (C. Lambertson).

1953: USN Air Tables Published.

1957: Development of saturation techniques: The Genesis Project (Bond).

1959: Nitrox diving methods first published in USN Diving Manual.

1962: First commercial heliox dive to 420 fsw (Wilson). Buhlmann successfully demonstrates ‘gas sequencing’ techniques on a 1,000 fsw dive. First saturation dive to 200 fsw (Link).

1965: First commercial saturation dive to 250 fsw using the Westinghouse Cachalot System.

1969: Walter Stark introduces the ‘ElectroLung’ mixed gas rebreather for $2,500, subsequently bought by Beckman Instruments. Beckman shuts down division in 1970 after a number of fatalities.

1970: First recorded incident of High Pressure Nervous Syndrome (HPNS). NOAA launches enriched air nitrox program.

1970: Biomarine Industries (a General Electric (GE) spin-off company) launches CCR 1000 mixed gas rebreather, a predecessor of Carleton Technology’s Mk 15/16 used by the U.S. Navy.

1970-1980: A variety of units like the GE Model 1400 (Mk-10), Shadow Pac, Westinghouse KSR-5, STM 300, Sterling Electronics SS-1000, Normalair-Garrett Deep Dive 500 hit the market. None of these products survive.

1977: First unsuccessful open circuit special mix dive in the sport diving community (Smith, Holtzendorff—Wakulla Springs).

1979: NOAA nitrox diving methods published in NOAA Diving Manual 2nd Edition.

1980: First successful special mix sport dives at Diepolder II to 360 fsw (D. Sweet).

1982: NewtSuit, a one atmosphere hardsuit becomes operational.

1982: ORCA Industries launches the first consumer dive computer called the EDGE.

1986: The International Association of Nitrox Divers (IAND) is formed by Dick Rutkowski, to provide nitrox training to sport divers.

    Professor Theodore Schwann in 1853 applies for a patent, never given, for a rebreather that he used in his physiology class. reference: Rebreather World, but I also have pictures from the Patent office. Ill send them to you if you like.

    Do you have pictures of Steven Hale’ apparatus?

    Title: Ronda totally unbiased wife of Bob Hollis

    I see that two rebreathers were mentioned in 1995 yet no mention of the Phibian the rebreather that Bob Hollis and Oceanic presented at DEMA. Granted all the years of hard work and dreaming came to an end in front of a 92 year old Federal Judge, he didn’t seem to grasp the technology etc.
    Anyway Bob kept dreaming, he had this goal since diving the electro lung in the early or mid 60’s.
    He knew that Fed OSHA had to change it’s position on Nitrox or there would be no future for rebreathers. So he hired a lobbyist in Washington to work on getting a bill passed changing the law. PADI was also starting down that path and so John Cronin and Bob signed an agreement to move forward.
    With help of congressman Jerry Lewis the bill was passed. The Hollis rebreathers were finally introduced for recreational market in 2012 (the Prism) and the Explorer in 2014.
    Of course I am totally unbiased, but I do remember living through it.
    It really was a wonderful study of the history of rebreathers, I did enjoy it.
