The narrative follows Dr. Wu Lien-teh, a pioneering figure in public health who, over a century ago, identified the airborne transmission of a deadly pneumonic plague in Northeast China. Despite facing ridicule, he successfully implemented quarantine measures and designed the first iteration of the N95 mask, which played a crucial role in controlling the outbreak. Coauthored by his great-granddaughter, the book highlights his contributions and encourages young readers to embrace scientific inquiry and community safety through historical context and engaging illustrations.
