I don't know which book the previous reviewer was reading, but it wasn't this one. Professor Wistrich's book is intended as a reference work, providing brief biographies of important or significant persons in Germany under the Nazi regime. It is not intended to provide a comprehensive biography of every member of the Nazi Party, nor to be a compendium of evil-doers, and it does neither. For example, it includes listings for Bertolt Brecht (playwright and poet), Otto Dix (German-expressionist painter), Albert Einstein (Nobel Prize-winning physicist), and Kathe Kollwitz (Socialist and painter)-- none of them Nazis. The big-name Nazis are there, but so are church leaders, artists, scientists, and business people, of a variety of political and ideological orientations, some of them offering active resistance to National Socialism.
The book is a biographical dictionary, providing a ready reference and point of departure for further research by the serious student. If I have a criticism, it is in some of those selected for inclusion-- a necessarily subjective decision, as the author acknowleges.
The previous reviewer's contention that Wistrich cites four of his own works in the bibliography again left me wondering what book he had read. In my copy, the author cites a grand total of ONE of his own works. Nor is the book the protracted drumbeat about how evil the Nazis were that the previous reviewer would have us believe it is, though failure to acknowledge the fact would be a falsification of history worthy of an ideologue-- not a historian.
