The National Academy of Sciences is a private, nonprofit institution that was established under a congressional charter signed by President Abraham Lincoln in 1863. It recognizes achievement in science by election to membership, and -- with the National Academy of Engineering and the National Academy of Medicine -- provides science, engineering, and health policy advice to the federal government and other organizations.
