Economist, Albert Schweitzer Professor of Economic Development, Columbia University, 1968-1973. Barbara Ward Jackson (Baroness Jackson of Lodsworth; Columbia University L.H.D., 1954) co-authored the book ONLY ONE EARTH; THE CARE AND MAINTENANCE OF A SMALL PLANET with bacteriologist, René Dubos. The book was commissioned by the United Nations Conference on the Human Environment and was funded principally by Columbia University's Albert Schweitzer Chair. The authors had the assistance of an international committee of corresponding consultants consisting of 152 individuals from 58 countries.

Correspondence, memoranda, manuscripts, audio tapes, and printed materials relating to the book ONLY ONE EARTH. The correspondence files are chiefly photocopies of letters and comments from the international committee, letters and memoranda of Jackson's staff and letters from Dubos to Jackson. There is one cataloged letter from Hubert H. Humphrey. The manuscript consists of numerous versions with corrections by the authors, the final edited manuscript for the publisher and printer and page proofs. Also, files relating to publicity, serial rights, and reviews for the book. In addition, there is an audio tape package (4 cassettes) entitled "The International Development Strategy: an In-depth Discussion" (Schloat Productions, 1973). A number of the panel members were Columbia University faculty members.
