Daniel Burros was the anti-Semitic activist who shot himself at twenty-eight when the New York Times ran a front-page revelation of his Jewish background on Halloween, 1965. His life had been a puzzling one. How did the most pious little boy in his Queens neighborhood become an adolescent admirer of the German Army, then as aspiring exterminator of Jews, who loved uniforms, Nazi relies and the slogan ""Kill!""? The authors give no final answers to this sort of question, but they have done an impressively thorough research job on Burros, his family, and the far-far-right organizations he belonged to (including the American Nazi Party and the Ku Klux Klan). They have also delved into the literature on Jewish and Gentile anti-Semitism. Rosenthal and Gelb are members of the Times editorial staff and had direct contact with the Burros story. With a minimum of committee prose and cheap psychologizing, they have managed to reconstruct a great many conversations, climates, and twisted bonds. Special promotion, general interest--and much more virtue than might have been expected, given the sensational topic.
