Sara Little Turnbull, Whose Bra Cup Design Became the N95 Mask
Check out this piece from Mental Floss that highlights the life and work of Sara Little Turnbull.
The coronavirus pandemic has made something of a celebrity out of the N95 mask, a particle-filtering face covering that’s long been used to protect wearers from inhaling or exhaling pathogens. (The “95” refers to the fact it can block 95 percent of airborne particles.)
Like most nondescript and pervasive products, not many people stop to think about where it came from. Now, owing to the attention placed on it as a key tool in the health care professional’s fight against coronavirus, the woman behind the mask has come to the forefront. Her name is Sara Little Turnbull, and she designed what would become the N95 based on the shape of a bra cup.
