William Hung was the most learnèd scholar of Classical Chinese at Harvard and mentored several generations of Harvard students. (Since he did not have a PhD, however, he was never allowed to supervise dissertations.)
Here is a story from his memoir, describing his college days at Ohio Wesleyan:
Russell B. Miller (the object of much conniving because he owned the only automobile in town) taught Greek. The text he used in Hung's class was the Four Gospels. Miller would call on individual students to read the text and translate the passage into English, but for a long time, he did not call on the lone Chinese student in the class. When he finally did, Hung stood up and gleefully recited the whole chapter, from memory, in Greek! He never called on Hung to translate again.
