The National Academy of Sciences is a private, nonprofit, selfperpetuating
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 govern
ment 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 mem
bers, sharing with the National Academy of Sciences the responsibility for advis
ing 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 pro
viding 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.
