“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. Eyes smarted painfully and watered with gas smelling like petrol or garlic from gas shells.Editor’s Note, May 11, 2022: This article previously suggested that John Haldane was the first person to invent a gas mask. Smoke helmet made darkness worse so tore it off. The bag was put over the head and the mouth of the bag was tucked within collar of the tunic. Later he describes a more sophisticated form of gas mask: 'Gas helmets put on - merely flannel bags with two pieces of celluloid for seeing through. We have to take a decent bite of this cotton waste when we tie the respirators on.' Lance Corporal Ramage alludes to this problem in his diary: 'Respirators are now made of cotton waste which are now and then wetted with some clear liquid carried by the sergeant. Protection was initially non-existent, and early gas-masks or 'respirators', once introduced, offered only a minimal improvement. With the establisment of gas as a weapon used by both sides in the First World War, a major concern of the troops was the effectiveness of their protection against its effects.
