Gordon D. Hall
Gordon D. Hall (1921-2001) was a political researcher, speaker, and archivist of radical and fringe political groups--both left and right--in America. Later with the assistance of Grace Hoag and other volunteers he established the Hall-Hoag Collection of extremist political material at Brown University.
Gordon Hall interviewed and publicly debated a number of political extremists in the 1960s ranging from Malcolm X of the Nation of Islam to George Lincoln Rockwell of the American Nazi Party. For a while he published a political newsletter titled Left Right Center.
