John Leighton Stuart was a missionary educator, the first President of Yenching University and later United States ambassador to China. He was a towering figure in U.S.-Chinese relations in the first half of the 20th century, a man TIME magazine called "perhaps the most respected American in China." According to one Chinese historian, "there was no other American of his ilk in the 20th century, one who was as deeply involved in Chinese politics, culture, and education and had such an incredible influence in China."
