JEREMIAH CURTIN took the degree of Bachelor of Arts at Harvard College in 1863, having been a member of the last college class that studied their required mathematics under me as Assistant Professor. I found young Curtin’s personal appearance and his mental processes unusual and interesting. He was a good scholar in general, with an extraordinary capacity for acquiring languages. In his autobiography (unpublished) he states that seven months and a half before he entered Harvard College he did not know one word of Latin or Greek, but at the admission examination he offered more of each language than was required. At the time of his death, 1906, he knew more than sixty languages and dialects, and spoke fluently every language of Europe and several of the languages of Asia.
