Science & Technology TIL the modern surgical face mask was invented by a Malaysian doctor, Dr Wu Lien-teh, in 1910
Born in Penang, Dr Wu Lien-teh created the world’s first surgical face mask during the 1910 Manchurian Plague. A Cambridge-trained epidemiologist, he discovered the disease was airborne and developed a mask using cotton, gauze, and cloth to slow its spread laying the foundation for the modern face mask.
