THE NATIONAL ACADEMIES
Advisers to the Nation on Science, Engineering, and Medicine
The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Ralph J. Cicerone is president of the National Academy of Sciences.
The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Charles M. Vest is president of the National Academy of Engineering.
The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Harvey V. Fineberg is president of the Institute of Medicine.
The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy’s purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Ralph J. Cicerone and Dr. Charles M. Vest are chair and vice chair, respectively, of the National Research Council.

Although the reviewers listed above have provided many constructive comments and suggestions, they were not asked to endorse the conclusions or recommendations, nor did they see the final draft of the report before its release. The review of this report was overseen by Leslie Z. Bennett, University of California-San Francisco and Ann Arvin, Stanford University School of Medicine. Appointed by the NRC, they were responsible for making certain that an independent examination of this report was carried out in accordance with institutional procedures and that all review comments were carefully considered. Responsibility for the final content of this report rests entirely with the authoring committee and the institution.
The Committee expresses its appreciation to Karen Goldenthal who served on this panel until July 2011. The Committee also extends its appreciation to Judith Hewitt for the white paper Developing Animal Models for Use in Animal Rule Licensure: The NIAID Approach. Finally, the Committee thanks the speakers who addressed the Committee in the public meetings of September and November 2009, and February 2010.
Lastly, and certainly most importantly, the Committee wishes to thank the diligent efforts of the ILAR leadership and staff who provided many levels of support to this endeavor. We are especially thankful to Dr. Lida Anestidou for her tireless work in guiding and helping craft this report while concomitantly assuming unanticipated extra duties for ILAR. The Committee very much appreciated the technical input and teamwork provided by Dr. India Hook-Barnard from the Board on Life Sciences. We also want to posthumously recognize the great support the Committee received from Ms. Kathy Beil, who made sure we got to the right places at the right time during the active period of the committee’s meetings in Washington D.C.
