The Deep Sea Diving Company Limited patented an atmospheric diving suit in 1897 where the atmospheric character was not realised. The patent describes a suit in which the movement of the joints is made possible by applying air pressure to the inside as well. The air supplied through hoses is blown out into the water through a return hose. The position of the opening of the return hose determines the internal pressure. A suit that has certainly not been used to dive at great depth. It is unclear whether the suit was actually produced.
Therebreathersite was founded by Jan Willem Bech in 1999. After a diving career of many years, he decided to start technical diving in 1999. He immediately noticed that at that time there was almost no website that contained the history of closed breathing systems. The start for the website led to a huge collection that offered about 1,300 pages of information until 2019. In 2019, a fresh start was made with the website now freely available online for everyone. Therebreathersite is a source of information for divers, researchers, technicians and students. I hope you enjoy browsing the content!
