The invention of the face mask wasn't a single event but rather a series of improvements over time. While several individuals contributed to its evolution, Dr. Wu Lien-teh is widely credited with creating a significant improvement that served as a forerunner to modern masks.
Dr. Wu Lien-teh's Contribution
During the 1910 pneumonic plague outbreak in Manchuria and Mongolia, Dr. Wu Lien-teh, a Chinese-Malaysian epidemiologist, significantly enhanced existing European mask designs. He developed a multi-layered mask using gauze and cotton, effectively protecting both the wearer and others from infection. This "Wu mask" is considered a crucial step in the face mask's development. His groundbreaking work established lifesaving blueprints for disease control, even more significant given its impact over a century before the COVID-19 pandemic.

Evolution of Face Masks
While Dr. Wu Lien-teh's design was pivotal, the face mask's history continues:
- Early 20th Century: Surgical masks appeared in operating rooms in Germany and the USA during the 1920s. [^5] These early designs were primarily focused on preventing surgical contamination.
- Mid-20th Century: Cloth face masks were largely replaced by surgical masks made from nonwoven fabric (via a melt-blowing process) in the 1960s. [^1]
- Late 20th and Early 21st Century: The N95 mask, featuring a highly effective filter material invented by Peter Tsai in the 1990s, became a vital tool in personal protective equipment. [^6]
It's important to note that the evolution of the face mask involved contributions from many individuals and countries. The claim that Otto Graham or Vernon McMillan invented the face mask is disputed and lacks widespread support compared to the evidence supporting Dr. Wu Lien-teh's critical contribution. [^3]
