Sreća vaša što mi je disk sa avionima na poslu, pa ću ovako ''iz glave'' jedno pitanje:

Ko je izmislio prvu zaštitnu masku (''gasmasku'') sa filterom i koje godine je ušla ''u naoružanje''?

Pa... zavisi koga pitas Englezi kazu:

In 1915, American chemist and inventor credited with the invention of the gas mask [4] James Bert Garner read a newspaper article describing a gas attack on British forces which he hypothesized had employed chlorine gas. Remembering experiments he had performed while teaching at the University of Chicago, he set about creating the first gas mask which he tested on two of his associates in a gas filled chamber. Following the successful completion of the test, he provided the results to the British government.[5]
Garner's mask was the first to be used on the Western front during World War I.[6]

The British Royal Society of Chemistry claims that British scientist Edward Harrison developed the first practical gas mask for mass production, a claim supported by a thank-you note written by Winston Churchill.[7]

Rusi kazu ovako:

Первый в мире фильтрующий угольный противогаз был изобретен русским ученым Николаем Дмитровичем Зелинским в 1915 г. Был принят на вооружение армий Антанты в 1916 г.

Pretpostavljam da je ovo drugo pravi odgovor, tj. da budemo formalni:

Nikolaj Dmitrovic Zelinski 1915 g, u naoruzanje Antante uvedena 1916.

Da ali Sirius rece sa filterom

Isto jedan deo sa Wikipedie:

"The gas mask was patented on June 12, 1849, by American Lewis Haslett in Louisville, Kentucky. It was an "Inhaler or Lung Protector," issued for an air purifying respirator. Haslett's device filtered dust from the air.[1]

Early versions were constructed by the Scottish chemist John Stenhouse in 1854 and the physicist John Tyndall in the 1870s.

One such design began as a "Safety Hood and Smoke Protector" invented by African American inventor, Garrett A. Morgan in 1912, and patented in 1914. It was a simple device, consisting of a cotton hood with two hoses which hung down to the floor, allowing the wearer to breathe the safer air found there. In addition, moist sponges were inserted at the end of the hoses in order to better filter the air. Morgan won acclaim for his device when in 1916 he, his brother, and two other volunteers used his device to rescue numerous men from the gas and smoke-filled tunnels beneath Lake Erie in the Cleveland Waterworks."
