A postcard mailed in March of 1911 to announce the American Library Association Conference in Pasadena, California provides a link to one of Wisconsin’s longtime special librarians. When Clarence S. Hean received this postcard he had been the Agricultural College Librarian and the University of Wisconsin for three years. He didn’t complete his service in that position until June, 1952, a span of 44 years. The library he directed is now the Steenbock Memorial Library. A group of letters exchanged with Nobel Laureate Joshua Lederberg relating to Hean’s retirement is located here. The 1911 ALA Pasadena Conference was the conference at which Theresa West Elmendorf was elected the first woman president of the American Library Association. Elmendorf is a member of the Wisconsin Library Hall of Fame.
