Dräger 1919 und 1920 Versuchgeräte
Shortly after the First World War Drager built a some test devices. After searching in many books and archives it has not been possible to identify this device. If you know which devices these pictures show I would like to hear from you!
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!
