How a secret, last-minute legislative maneuver created America's most prestigious scientific advisory body.

In short: In the final hours of an 1863 congressional session, a group of scientists bypassed formal debate to establish the National Academy of Sciences. Designed to provide independent, pro bono advice to the federal government, this institution remains a cornerstone of American research, despite its controversial and rushed origins.

The National Academy of Sciences (NAS) was born from the efforts of the Scientific Lazzaroni, an informal network of researchers based near Cambridge, Massachusetts. Figures like Alexander Dallas Bache, Louis Agassiz, and Benjamin Peirce orchestrated the academy's creation, intentionally excluding Joseph Henry, who feared such a body would clash with American democratic values. By leveraging Senator Henry Wilson, the group pushed an incorporation bill through the Senate and House during the frantic final moments of the 1863 legislative session, ensuring it was signed by President Abraham Lincoln without public scrutiny.

This clandestine birth sparked significant resentment among the broader scientific community, as many felt excluded from the process. Despite these rocky beginnings, the NAS was chartered to serve as an independent, non-governmental adviser to the nation. Under its congressional mandate, the academy provides objective scientific and technical expertise to any government department whenever requested. Crucially, the academy receives no payment for these services, maintaining its status as a trusted, independent resource rather than a standard executive agency.

Today, the NAS operates as a self-perpetuating body where existing members elect new peers for life based on distinguished research achievements. While the organization was once criticized for its lack of diversity—admitting in 1989 that female membership was at a dismal trickle—it now includes over 3,200 living members across six scientific classes. Governed by a 17-member council, the academy continues to influence national policy through its scholarly journal, PNAS, and its extensive network of committees, proving that a project once dismissed as elitist has become the pinnacle of American scientific recognition.
