Franz Neumann's "Behemoth" is now regarded as a modern classic of social science. Published in 1942 during the decision-making phase of World War II, the book provided the first comprehensive account of Hitler's Germany from the perspective of an émigré and temporarily served as a sort of manual for American authorities in their war efforts against Hitler. Neumann's extensive and knowledgeable analysis remains a unique challenge to interpretations of fascism. The work is now available in a new edition featuring a foreword by Alfons Söllner, who outlines Franz Neumann's biography as the formation of an epoch-defining scholar—the "political scholar"—and includes an afterword by Michael Wildt, who places "Behemoth" in the context of international Nazi research and particularly questions why its reception has evolved throughout history.
