Series 2: Research and Discovery of the Transforming Principle, 1912-1999

This series contains articles, correspondence, notes, reports, newsletters, photographs, negatives, and manuscript drafts leading to Avery's discovery of the transforming principle and research based on and succeeding the discovery. The series is divided into three subseries: Preliminary Research, Excerpts from the Rockefeller Institute Reports, and Succeeding Research. The Preliminary Research Subseries contains a copy of The Journal of Experimental Medicine's 35th anniversary reprint of Oswald Avery, Colin MacLeod, and Maclyn McCarty's article, "Studies on the Chemical Nature of the Substance Inducing Transformation of Pneumococcal Types," which was originally published in 1944. The subseries also contains original pages from Avery's laboratory notebooks that document experiments in his laboratory during 1940 to 1946.
