There remains one other activity to be mentioned in Mr. Nelson's city-wide ministry. In 1930 Mayor Murray Seasongood appointed him to the Board of Directors of the University of Cincinnati, a board commonly known as the Trustees. It was a distinguished appointment, characteristic of Mayor Seasongood's primary emphasis on the welfare of the city, and indicative of the confidence placed by intellectual and civic leaders in Mr. Nelson's judgment and ability. The Board was made up of eight business men and lawyers and concerned itself mainly with the financial problems of the University. Mr. Nelson's approach was to the human element in each situation with which this Board had to deal. He served in this capacity for eight years, and became "an acute, piercing trustee." The University Medical School has oversight of the Cincinnati General Hospital, and Mr. Nelson was troubled by the large number of cases of tuberculosis among members of the staff and the nurses and interns. The hours were long, the pay poor, and living conditions deplorable. He was very active in his support of the efforts by the authorities to bring about improvement in these conditions. He was chairman of the committee which interviewed candidates for the office of Dean of Woman, since many on the Board did not feel qualified to make such a selection. During the depression in the thirties when reduction of salaries and of department personnel became necessary, Mr. Nelson was instrumental in securing fair treatment for the individual teacher. He would ask if the teacher whose salary reduction was under consideration had a family and how many children. His colleagues considered him a very important agent in preserving morale during these difficult years, and the President and deans frequently sought his counsel. He was a firm believer in academic freedom. When the Engineering College arranged lectures for business men, he gave the plan his hearty support, and occasionally came under fire because of certain radical speakers. He was frequently the choice of the University as its representative on public occasions in the city. At the Commencement of 1924, the University of Cincinnati bestowed upon Mr. Nelson the honorary degree of Doctor of Laws, "as one who has ever striven to advance the government of the mind and spirit, and who by his own severe self-discipline and true humility has taught all of us to subdue ourselves to the imperishable laws of reason and faith."
