Brief History


In 1959 the philosopher and philanthropist, Obert C. Tanner, MA '37, and his wife, Grace A. Tanner, offered to underwrite the costs of creating a library within the department. On March 4, 1960, 150 people attended the ceremony during which the Tanners dedicated the library as a memorial to three sons of theirs who had died young.

The library collection has developed steadily over the years, from the original bequests of books by Professors Harold C. Brown, Henry W. Stuart, and Clarence I. Lewis, to the 8,500 volumes it houses today. The Tanners continued their patronage of the library over the next thirty years and in 1990 they helped to secure its future by enhancing an endowment they had established in 1961. Other members of the Tanner family have also continued to support the library through the years.
