"The need of another literary society had been felt for a long time. Several had talked of organizing one, but nothing was done until the winter term in 1904. A constitution with by-laws was then framed and the draft was read at a meeting of Per Gradus on March 21, 1904. Seven members and ex-members of Per Gradus signed the draft and petitioned the faculty for permission to organize a new literary society, a permission that was readily granted. But the society was, as yet, nameless. Dr. Thomas being called upon to propose a name suggested Ad Altiora. This was adopted and Ad Altiora was now born and baptized."
