The N95 mask has a fascinating and long history - from Fast Company:
The untold origin story of the N95 mask
The most important design object of our time was more than a century in the making
It’s hard to think of a symbol of COVID-19 more fraught than the N95 respirator. The mask fits tightly around the face and is capable of filtering 95% of airborne particles, such as viruses, from the air, which other protective equipment (such as surgical masks) can’t do. It’s a life-saving device that is now in dangerously short supply. As such, it has come to represent the extreme challenges of the global response to COVID-19.
How did a flimsy polymer cup become the most significant health device of the 21st century? It all started in 1910 with a little-known doctor who wanted to save the world from one of the worst diseases ever known.
The genesis was a virulent illness in 1950 in Manchuria - a Chinese doctor came up with a prototype and showed it to someone:
The Chinese Imperial Court brought in a doctor named Lien-teh Wu to head its efforts. He was born in Panang and studied medicine at Cambridge. Wu was young, and he spoke lousy Mandarin. In a plague that quickly attracted international attention and doctors from around the world, he was “completely unimportant,” according to Lynteris. But after conducting an autopsy on one of the victims, Wu determined that the plague was not spread by fleas, as many suspected, but through the air.
Expanding upon the surgery masks he’d seen in the West, Wu developed a heartier mask from gauze and cotton, which wrapped securely around one’s face and added several layers of cloth to filter inhalations. His invention was a breakthrough, but some doctors still doubted its efficacy.
“There’s a famous incident. He’s confronted by a famous old hand in the region, a French doctor [Gérald Mesny] . . . and Wu explains to the French doctor his theory that plague is pneumonic and airborne,” Lynteris says. “And the French guy humiliates him . . . and in very racist terms says, ‘What can we expect from a Chinaman?’ And to prove this point, [Mesny] goes and attends the sick in a plague hospital without wearing Wu’s mask, and he dies in two days with plague.”
Heh - showed the Frenchman a thing or two...
Lynteris is Christos Lynteris - a senior lecturer at the Department of Social Anthropology at the University of St. Andrews and an expert in medical mask history. Much more at the site - some interesting reading for a quiet day at home.
