The apparatus had been invented some years earlier by Hermann Stelzner, an engineer at the Dräger company, [43] for mine rescue. [44] In the 1930s, after some tragic accidents in the 1920s, the United States Navy began to equip Porpoise-and Salmon-class submarines with primitive rebreathers called Momsen lungs, which were in use until the 1960s.
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 Italians developed similar rebreathers for the combat swimmers of the Decima Flottiglia MAS, especially the Pirelli ARO. [66] In the U.S. Major Christian J. Lambertsen invented an underwater free-swimming oxygen rebreather in 1939, which was accepted by the Office of Strategic Services. [67]
Some military rebreathers (for example the US Navy MK-25 and the MK-16 mixed-gas rebreather), and the Phibian CCS50 and CCS100 rebreathers, were developed by Oceanic.

A scuba set is characterized by full independence from the surface during use, by providing breathing gas carried by the diver. Early attempts to reach this autonomy were made in the 18th century by the Englishman John Lethbridge, who invented and successfully built his own underwater diving machine in 1715, but though the air supply was carried in the diving apparatus, it relied on surface ...
Around 1825, he invented ... Before open-circuit SCBA's were developed, most industrial breathing sets were rebreathers, ...
The waist belt buckles were usually quick-release, and shoulder straps sometimes had adjustable or quick-release buckles. Many harnesses did not have a backplate, and the cylinders rested directly against the diver's back. The harnesses of many diving rebreathers made by Siebe Gorman included a large back-sheet of reinforced rubber. [citation ...
Many diving rebreathers are descended from it. However, there were earlier underwater uses of rebreathers: Davis Escape Set for use in emergency by submariners from 1927 onwards; Siebe Gorman Salvus invented in the 1900s and first used in mines and by firemen; The rebreathers used by the Italian Decima Flottiglia MAS frogmen in World War II
