His passing was noted by a respectful obituary
in today's New York Times. I knew of him because of this study :
The author or editor of many books, Mr. Finger wrote "American Jewry During the Holocaust" (1984), published by the American Jewish Commission on the Holocaust. The report of the commission, of which Mr. Finger was research director, concluded that the major Jewish organizations in the United States had not done all they could to save victims of the Holocaust, still a controversial position at the time of publication. The chairman of the commission was former Justice Arthur J. Goldberg of the Supreme Court.
