Norman Lambertsen

Norman Lambertsen was an influential American physician and inventor, best known for his pioneering work in underwater diving and hyperbaric medicine. He developed the closed-circuit rebreather, a device that recycles exhaled air, allowing divers to stay underwater for longer periods without creating bubbles, which is crucial for stealth in military operations. Lambertsen's innovations contributed significantly to both military and recreational diving, enhancing safety and efficiency. Additionally, he made advances in hyperbaric therapy, which uses increased atmospheric pressure to treat various medical conditions. His work has had a lasting impact on both diving technology and medicine.
