Personal, administrative, political, and investigative files of Nickerson. The papers deal almost entirely with his eight years as County Executive, and consist of correspondence, memoranda, manuscripts of speeches, notes, press releases, photographs, and clippings. Among the major correspondents are James A. Farley, Hubert H. Humphrey, Robert F. Kennedy, Edward I. Koch, and Percy E. Sutton. The Investigation Files, which amount to nearly half the collection, document investigation into corruption and mismanagement in numerous Long Island businesses and governmental departments. These investigations, instigated and overseen by Nickerson, were carried out largely by the Commissioner of Accounts, Milton Lipson, and later by Samuel Greason, the first governmental ombudsman in the United States. These files consist primarily of memoranda, transcripts of hearings, payroll and financial accounts, notes, and tape recordings.

Carman, Dwight David Eisenhower, Robert F. Kennedy, Arthur Hays Sulzburger, and Herbert Bayard Swope.
