From the publisher

An inspiring picture book biography celebrating Dr Wu Lien-teh, a hero of science who braved an epidemic to create a new kind of mask - a mask that, a hundred years later, continues to save lives today. Written by an ER doctor and vetted by experts at MIT, this fascinating true story is perfect for fans of Little People, Big Dreams.

Growing up in Malaysia, Wu Lien-teh had always loved science and wanted to be a doctor. His studies took him around the world and in 1910 he brought his expertise to China to fight the plague. There he overcame discrimination to promote trailblazing measures that will be familiar to readers today - including encouraging people to wear a face covering he designed from layers of cloth and gauze: the first version of the N95 mask.

Written by Wu Lien-teh's great-granddaughter, who is now an ER doctor who relied on his life-saving invention during a pandemic a century later, and charmingly illustrated by Lisa Wee, this is an inspiring and fascinating biography about an unknown hero of science.
