*********************

A closed circuit, recycled oxygen device was developed in 1876 by Henry Fleuss. The English inventor originally intended the device to be used in the repair of a flooded ships chamber. Henry Fleuss was killed when he decided to use the device for a 30 foot deep underwater dive. What was the cause of death? The pure oxygen contained within his device. Oxygen becomes a toxic element to humans when under pressure.

Soon before the closed circuit oxygen rebreather was invented, the rigid diving suit was developed by Benoît Rouquayrol and Auguste Denayrouze. The suit weighed about 200 pounds and offered a safer air supply. Closed circuit equipment was more easily adapted to scuba in the absence of reliable, portable, and economical high pressure gas storage vessels.

Robert Boyle first observed a bubble in the eye of a distressed viper used in compression experiments, but it wasn’t until 1878 that a man named Paul Bert linked the formation of nitrogen bubbles to decompression sickness, suggesting that slower ascents out of the water would help the body eliminate nitrogen safely.
