About the Authors

Author Shan Woo Liu is the great granddaughter of Wu Lien-teh. She is an emergency medicine physician at Massachusetts General Hospital in Boston, and an Associate Professor of Emergency Medicine at Harvard Medical School.

Shan's daughter, Kaili, began writing Masked Hero: The Story of Wu Lien-teh as part of a first-grade project in 2020, soon after the COVID-19 pandemic broke out in the United States.

Masked Hero is the first book written by Shan and Kaili. They are proud to share the story of Dr. Wu, and to help children understand that even the simplest acts, such as wearing a mask, can make us all powerful, brave, and hard working heroes, just like Wu Lien-teh!
