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. On the authority of the charter granted to it by the U.S. 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 ser-
vices 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, on 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 Acad-
emy, 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.
The Transportation Research Board is one of six major divisions of the National Research Council. The
mission of the Transportation Research Board is to provide leadership in transportation innovation and prog-
ress through research and information exchange, conducted within a setting that is objective, interdisciplinary,
and multimodal. The Board's varied activities annually engage about 7,000 engineers, scientists, and other
transportation researchers and practitioners from the public and private sectors and academia, all of whom
contribute their expertise in the public interest. The program is supported by state transportation departments,
federal agencies including the component administrations of the U.S. Department of Transportation, and other
organizations and individuals interested in the development of transportation. www.TRB.org
