Correspondence, notes, manuscripts, documents, photographs, audio tapes, and printed material of Louis G. Cowan. The files document Cowan's activites at CBS and Brandeis University, and in many other capacities. Approximately one-third of the collection consists of records and studies of the Broadcast Institute of North America. The papers also reflect a number of Cowan's various interests such as posters; the earliest item in the collection, a letter from General Charles P. Stone, 1885, is indicative of Cowan's active interest in the history of the Statue of Liberty. Among the prominent correspondents are Jacob Bronowski, Hubert H. Humphrey, William Phillips, and Jonas Salk.
