Because of the novel coronavirus, it is useful for many people to wear masks to avoid illness. In fact, masks have been helping humans for centuries. Let’s take a look at something about masks.
1st century
During that period, many people in Roman Empire lived a hard life and had to work underground in mines to support their families. But after several years’ work, most of them had difficulty breathing normally and finally died. To solve this problem, Pliny the Elder (23-79 AD), a Roman philosopher and naturalist, recommended the use of animal bladder ( 膀 胱 ) skins to stop dust from being taken in. After that, his idea was considered the very first recorded mask invention.
16th century
Early inventions did not stop with Pliny. Many centuries later, Italian artist and inventor Leonardo da Vinci (1452-1519), put forward a suggestion of using a wet cloth over the face to protect against the harmful chemicals.
19th century
The design of the mask took a big step forward in the 19th century. In 1848, American Lewis Hassley started to patent (注册) a protective mask for miners, which was a landmark. Masks at this stage were similar to gas masks. Later, in 1897, Polish-Austrian doctor Johann von Mikulicz-Radecki designed a simple mask made of one layer of gauze ( 纱 布 ), recommending medical workers to wear it to prevent infection. Since then, surgical masks have appeared.
20th century
In 1910, an epidemic broke out in Northeast China. Chinese doctor Wu Liande designed a cheap face mask called “Wu’s mask”. Made of two layers of surgical
gauze, it could be wrapped (缠绕) around the back of the head and tied in a knot. This mask was praised by experts around the world, as it was easier to make and had a lower production cost.
Modern exploration
With the development of science technology, the materials in masks have been improved to better protect its wearer. For example, in 2012 when China suffered from smog, mask models such as N95 and KN90 became highly popular. In the future, masks will continue to improve, hopefully so will the habits of humans.
