Bcd Buoyancy

Who invented the buoyancy control device (BCD)?
The jacket-style BCD has a history of gradual development. When SCUBA diving first kicked off as a hobby, BCDs weren't used at all, and the only 'buoyancy adjustment' came from the weights (used to overcome the diver's (un)natural buoyancy) and the lungs. Oh, and swimming to stay off the bottom and kicking the reef to bits wasn't considered such a no-no at that time.
Pilot-style 'Mae West' front-mounted lifejackets were adapted for use as surface support post-dive. Inflation was by integral air cylinder or CO2 cartridge.
Maurice Fenzy had the idea of attaching an oral inflation hose, allowing the lifejacket to be partially inflated/deflated underwater, or inflated at the surface (just as OWD students are taught to do with modern BCDs), thus creating the adjustable buoyancy lifejacket (ABLJ).
Then someone (possibly Fenzy again) had the idea of attaching the inflation hose to the cylinder air supply and saving all that complicated effort of removing and replacing the scuba mouthpiece.
Then someone had the idea of integrating the cylinder harness and ABLJ into a combined unit--the jacket style BCD. The first one was manufactured by ScubaPro in 1971.
As ever, the 'new' technology was pioneered by cave divers, who used plastic bottles/jerrycans tied to their gear to adjust their buoyancy during cave explorations where they were carrying extra tanks and equipment.
And as ever, diving's heavyweights at the time decried the BCD as a potential deathtrap due to its 'complexity', and its propensity to float an unconscious diver face down at the surface. Despite this, nowadays, nearly every sport diver trains with and dives on BCDs.
