The Cullinan Papers would be of considerable use to anyone writing a biography of Sir Thomas Cullinan.

Perhaps the most important part of the papers is the material (notebooks, correspondence, telegrams and notes) on the campaign against the Germans in S.W. Africa during the first World War. The scrapbooks, loose press clippings and other miscellaneous items in the collection would be of interest to the political researcher, particularly for the period 1905-1910. There is also a little of mining interest for the industrial historian.
