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 govern -
ment. 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.
