The Federation of American Scientists (FAS) provides science-based analysis of and solutions to protect against catastrophic threats to national and international security. Specifically, FAS works to reduce the spread and number of nuclear weapons, prevent nuclear and radiological terrorism, promote high standards for nuclear energy’s safety and security, illuminate government secrecy practices, as well as prevent the use of biological and chemical weapons.
FAS was founded as the Federation of Atomic Scientists in November 1945 (and was rebranded as the Federation of American Scientists in February 1946) by many of the Manhattan Project scientists who wanted to prevent nuclear war, and it is one of the longest serving organizations in the world dedicated to reducing nuclear and other catastrophic threats and informing the public debate by providing technically-based research and analysis on these issues.
FAS is a non-profit membership organization, with members from the academic, non-profit and government communities. For more information on FAS membership and to join, please visit our Membership page.
FAS hosts a wide range of events, including briefings and symposiums, with government officials, policy experts, scientists, and engineers on issues related to international and national security.
FAS convenes awards ceremonies to recognize and commend contributions by outstanding scientists and political leaders to science and international security. The awards include the FAS Public Service Award, the Hans Bethe Award, and the Richard L. Garwin Award.
FAS staff and adjunct fellows comprise a highly skilled and dedicated team with professional experience in aeronautical engineering, biology, biochemistry, chemistry, environmental science, law, nuclear engineering, physics, and political science. Members of the Board of Sponsors, including over 60 Nobel laureates, are influential figures from the scientific and international communities who endorse FAS’s mission. Advisory Board members work with FAS staff on projects of mutual interest, share professional expertise, and provide other methods of support to enhance the organization’s mission and programs.
