The Council on Foreign Relations was established in 1921, with support from the Rockefeller family, to provide a forum for government officials, corporate executives, journalists, students, and other interested parties to study and discuss world issues and the related impact on American foreign policy. The council publishes Foreign Affairs, a magazine that comes out six times a year, along with books and studies by its own scholars. Former president Leslie H. Gelb, once a columnist and editor at The New York Times, retired in 2003 after 10 years in the post, and was succeeded by diplomat Richard Haass. Prospective members must be US citizens (native-born or naturalized) and are nominated by an existing member.
