The file of correspondence with Fairfield Osborn (SZ/CF/1) includes a letter written to Zuckerman by Dr Osborn's father, Henry Fairfield Osborn of the American Museum of Natural History in New York, 14 November 1933, discussing Zuckerman's recently-published book Functional Affinities of Man, Monkeys, and Apes. The files of correspondence with later Presidents of the Foundation, Samuel H. Ordway and Russell Train, are slight and formal in nature.
The first sub-file of correspondence with Dr Robert Snider (SZ/CF/4/1) is concerned with Foundation business and in particular the Caribbean Commission Conference on demographic problems; the next (SZ/CF/4/2) relates to International Population Research, a consultancy service established by Dr Snider. The third (SZ/CF/4/3), relates to an International Indian Ocean Expedition, sponsored by the International Council of Scientific Unions (ICSU) Special Committee on Oceanic Research; Robert Snider was Coordinator of the Expedition.
The file on the Caribbean Commission Conference on Demographic Problems, 1957, consists of copies of the report of the conference and some of the papers presented, and a variety of background publications on population, human fertility, and demography. Zuckerman attended the Conference in an official capacity at the request of the Colonial Office.
