The papers pertain primarily to Bacon's personal and business activities, 1876-1926. His personal papers reflect his interest in politics, economics, science and linguistics; the business papers document his association with several companies, most notably Rowland Hazard's Solvay Process Company of Syracuse, New York. In addition, the collection contains personal papers of other Bacon and Hazard family members, including Rowland Hazard, 1763-1835; Joseph Peace Hazard, 1807-1894; Thomas Rutherford Bacon, 1850-1913; Caroline Hazard, 1856-1945; Helen Hazard Bacon, 1861-1925; and Leonard Bacon, 1887-1954. Material concerning these individuals is incomplete. The researcher is referred to the National Union catalog of Manuscript Collections for information on additional holdings of Bacon and Hazard family papers.
