A self-effacing, generous man, tall and physically active, Popkin was thought by some to be the best scholar at Harvard since the Revolution. He became the second Eliot Professor of Greek after the election of Edward Everett to the U.S. Congress. Everett, with his oratorical gifts to Interest, instruct, and amuse, was a difficult act for the reserved and bookish Popkin to follow. He did not care to show off his personality and devoted his classes instead to routine parsing and commentary on the ancient texts, much in the manner of his time. Though his students referred to him affectionately as "Old Pop," he was not a great success in drawing students to the classics. As a scholar he edited the Gloucester Oreek Grammar and Dalzel’s Collectanea Graeca. He never married ("I have too much impartial benevolence to narrow down my affections to one") and denied that he had ever told a student seeking a "miss" (remissio orationis) from class, "Ye ask, and ye receive not, because ye ask a-miss": "I have not wit enough; in the next place, I have too much wit, for I mortally hate a pun. Besides, / never allude irreverently to the Scriptures."
