Albert Einstein and the Emergency Committee of Atomic Scientists (ECAS) conducted a reform-based public communication campaign for the international control of atomic energy after the Second World War. The Committee raised funds and sought publicity for its proposed solution to the problem of war and the management of peace. Its solution was the institution of a supra-national or world government with more comprehensive powers than those of the United Nations. Submission to a world government would require disarmament and giving up "the secret" of the atom bomb. This was a radical proposal in light of the growing tensions of the Cold War and America's overwhelming concern with national security in what it perceived as a hostile world. A thematic analysis of the Committee's campaign literature indicated that the ECAS relied on fear and had reform as the primary goal, even though the Committee's incorporation papers stated that it had an educational mission. Analysis of the Committee's campaign also indicated that it cannot be easily classified under James Grunig's four models of public relations and suggests that publicity as an instrument of reform may be conceptually distinct from press agentry and public information.
