About Maurice Fernez
- Maurice Fernez (30 August 1885 - 31 January 1952, Alfortville, Paris, France) was a French inventor and pioneer in the field of underwater breathing apparatus, respirators and gas masks.
- He was pivotal in the transition of diving from the tethered diving helmet and suit of the nineteenth century to the free diving with self-contained equipment of the twentieth century.
- All Fernez invented apparatus were surface-supplied but his inventions, especially his mouthpiece equipped with a one-way valve, inspired the scuba diving pioneer Yves le Prieur.
- He was also a talented businessman who created a company to manufacture and sell the breathing apparatus he invented, and expanded its range of products to include gas masks, respirators and filters.
