![]() One stretcher bearer quoted in Chester’s article described being among the first to use the veil respirator:īut, I found using it in the gas cloud that after a couple of minutes one couldn't breathe and so it was pushed up over the forehead and we swallowed the gas. “Basically it was pads of cotton waste that were wrapped in gauze and soaked in a solution, sodium thiosulphate, which neutralized the effects of low concentrations of chlorine gas.īut it was far from a solution. Then Haldane’s first effort was a “makeshift” respirator, Sturdy told the BBC, called the “Black Veil” respirator. “Naomi was stationed outside the door, which had a window in it, with instructions that if any of them were incapacitated she should get them out as quickly as possible and perform artificial respiration on them,” Sturdy says.īefore Haldane and his team made innovations in keeping soldiers safe from gas, the suggested remedy on the front lines was holding a urine-soaked handkerchief or urine-soaked socks to the face, Chester writes. Haldane and his fellow researchers would expose themselves to gas and test its effects. The scientist’s lab was in his home, and he employed his daughter Naomi, then a teenager, as a research assistant, historian Steve Sturdy told the BBC. Haldane and his team were able to identify the gas used at Ypres as chlorine by examining discolored metal buttons on soldiers' uniforms.Īfter he returned to his home in Oxford, England, he started experimenting to find out what would keep the gas out. His job was to ID the kind of gas that was being used. Thirty years into his career, in 1915, Haldane was sent to Ypres after the battle, the BBC writes. He had also done previous work on how to protect miners from gas using respirators, according to Jerry Chester for the BBC.īut Haldane’s other big contribution didn’t just endanger birds: It endangered him and his family. Smithsonian has written about Haldane before, because he was the man who devised the idea of using canaries and other small animals in coal mines to detect odorless, deadly gases. He taught at several universities and developed medical remedies for common industrial ailments. But he wasn’t a practicing doctor: instead he was a medical researcher, writes the Science Museum in London. Haldane, born on this day in 1860 in Edinburgh, Scotland, got his medical degree in 1884. One of these scientists was John Scott Haldane, whose spectacular moustache (see above) would likely have prevented him from getting a good seal when wearing a gas mask. Unprepared for German forces to use chlorine gas as a weapon, many Allied soldiers suffocated, unprotected, during the Battle of Ypres in 1915.īut they gained protection thanks to the efforts of scientists who worked on the home front. The story has been updated to reflect Morgan’s contributions. In fact, Garrett Morgan, a Black inventor based in Ohio, filed a patent for a gas mask in 1914, a year before Haldane started researching his device. The filter shown below has an attachment at the bottom which contained a thin pad designed to filter out diphenylchlorarsine, an irritant (sternutator).Editor’s Note, May 11, 2022: This article previously suggested that John Haldane was the first person to invent a gas mask. ![]() These are often passed off as German masks, but are worth far less even though they are rarer. There are Belgian postwar (wartime?) conversions of these German leather masks they were modified with the French ARS plate and filter. Make sure the filter and filter attachment plate look like the one shown below in the photos. The body of the mask was made of chrome tanned sheepskin dipped in sealing oil to waterproof it. The main filtering agents used in the 11-C-11 model were activated charcoal and potassium carbonate. ![]() The filter should be ink stamped with this marking along with batch, date and sometimes maker marks. There is no asbestos to be found in any WW1 German gas masks.Īs the type of mask you're getting is the leather variant, which replaced the earlier rubberized cloth mask in June 1917, the filter is likely the 11-C-11 version introduced in May 1917. ![]()
