During the First World War the German army used poison gas for the first time, against Allied troops at Ypres, France in 1915. A soldier's only protection was to breath through a handkerchief or other small piece of fabric soaked in urine.
Out of necessity, Doctor Cluny Macpherson, from St. John's, Newfoundland, quickly came up with the idea of a gas mask made of fabric and metal. Using a helmet taken from a captured German prisoner, he added a canvas hood with eyepieces and a breathing tube. The helmet was treated with chemicals that would absorb the chlorine used in the gas attacks. He had invented the world's first gas mask. After a few improvements, Cluny Macpherson's helmet became the first gas mask to be used by the British army.
Inventor: Cluny Macpherson (1879-1966)
