David is a historian focusing on the Great Wall. He specializes in bringing to life this rich, colorful, and sometimes salacious material for visiting groups. His article “Raid of the Scorned Mongol Woman” was recently published in a scholarly journal, and he has collaborated with the photographer Jonathan Ball on “China’s Great Wall: The Forgotten Story,” a series of oversized photographs of Great Wall battle sites that has so far been exhibited in New York, San Francisco, and Palo Alto. David has been profiled by Peter Hessler in the New Yorker, has appeared on the Today Show, and has been featured in two Discovery Channel documentaries. He holds a BA in Asian Studies from Dartmouth, an MA in history from Beijing University, and a JD from Harvard Law School. With the exception of three years in law school, he has lived in China continuously since the 1980s. Before he began full-time research of Great Wall history, he was a consultant at McKinsey & Company.
