The founder of the American Nazi party and its leader until he was murdered in 1967, George Lincoln Rockwell was one of the most significant extremist strategists and ideologists of the postwar period. His influence has only increased since his death. A powerful catalyst and innovator, Rockwell broadened his constituency beyond the core Radical Right by articulating White Power politics in terms that were subsequently appropriated by the one-time klansman David Duke. He played a major role in developing Holocaust revisionism, now an orthodoxy of the Far Right. He also helped politicize Christian Identity, America's most influential right-wing religious movement, and welded together an international organization of neo-Nazis. All of these extremist movements continue to thrive today. Frederick Simonelli's biography of this powerful and enigmatic figure draws on primary sources of extraordinary depth, including declassified FBI files and manuscripts and other materials held by Rockwell's family and associates.
