|The apparatus pictured at left, devised in
1903 by the Dräger company of Germany, operated in a similar way as the
Siebe-Gorman self-contained devices. Draeger breathing devices and other
safety equipment grew so popular in the mine rescue business that the word "draegerman"
eventually became a synonym for an underground rescue worker (Webster's
Third New International Dictionary). The company, which still exists
today, claims to have manufactured two million gas masks for the German
Armed Forces during World War I.
