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. Around one and a half million were produced in 1916–1917.Editor’s Note, May 11, 2022: This article previously suggested that John Haldane was the first person to invent a gas mask. The PHG Helmet appeared in January 1916 and was similar to the PH Helmet but had a facepiece made of rubber sponge to add protection against tear gas. Around 14 million were made and it remained in service until the end of the war by which time it was relegated to second line use. The PH Helmet (Phenate Hexamine) replaced it in October 1915, and added hexamethylene tetramine, which greatly improved protection against phosgene and added protection against hydrocyanic acid. ![]() It had flannel layers of cloth-dipped in sodium phenolate and glycerin and protected against chlorine and phosgene, but not against tear gas. The exhale valve was needed because a double layer of flannel – one treated and one not – was needed because the solution attacked the fabric. It featured two mica eyepieces instead of the single visor of its predecessor, and added an exhale valve fed from a metal tube which the wearer held in his mouth. appeared in July 1915, replacing the simpler Hypo Helmet. The P (or Phenate) Helmet, officially called the Tube Helmet, Rather than having a separate filter for removing the toxic chemicals, they consisted of a gas-permeable hood worn over the head which was treated with chemicals. ![]() The P helmet, PH helmet and PHG helmet were early types of gas mask issued by the British Army in the First World War, to protect troops against chlorine, phosgene and tear gases.
