John K. Fairbank
Starting in 1966, Professor Twitchett and historian John K. Fairbank (who taught at Harvard) began plans for the first comprehensive history of China to be published in the English language. Originally expected to be a six volume set of books, the series expanded as time passed and eventually grew to the currently planned 15 volumes. While he was at Princeton, Twitchett worked closely with fellow Sinologist Frederick W. Mote (who had a related wartime experience).
