Jasper County Democrat, Volume 22, Number 37, Rensselaer, Jasper County, 6 August 1919 — First “Gas Masks.” [ARTICLE]

First “Gas Masks.”

The first apparatus to enable persons to enter a noxious inflammable atmosphere was called the “aerophore” and was the Invention of M. Denayrrouze, a French inventor and scientist. It was first tested at Chatham, England, 44 years ago, ’and was reported successful. Vast Improvements on this device, which comprised an air-pump and flexible tubing, have since been made, and these have saved the lives of hundreds in mine accidents and other disasters where rescue work would be impossible without their use.
