1952 Hesburgh           Discovered 1951 May 3 at the Goethe Link Observatory, Indiana University.
Named in honor of the Very Reverend Theodore M. Hesburgh, C.S.C., President of the University of Notre Dame since 1952. Father Hesburgh has an extraordinary record of public service in areas ranging from the humanitarian to the technical and scientific. During his 12 years as a member of the National Science Board he played a very important role in the founding of both the Kitt Peak National Observatory and the Cerro Tololo Interamerican Observatory. His support for CTIO during the 1964 period of inflation in Chile was decisive. Name proposed by F. K. Edmondson.
