Aaron L. Chapin graduated at Union College in 1853.

The evidence

• “He then resigned the pastoral charge of the church and became permanently connected with the school as the principal. He had fitted himself for college at De Ruyter Institute ; graduated at Union College in 1853, and completed the full course of studies at Union Theological Seminary, New York city, in 1856. From that time on till his death on May 20, 1902, a period of forty-four years, he was the president of the academy and of the college, and the history of the school for this almost a half century is in reality a part of his biography ; a part, because his life was even more extended than that of the school, for he was one year a member of the Wisconsin legislature, for four years the superintendent of public instruction, and for nine years a member of the state board of regents of the normal schools.”
