Paul Lerner traces the intertwined histories of trauma and male hysteria in German society and psychiatry and shows how these concepts were swept up into debates about Germany's national health, economic productivity, and military strength in the years surrounding World War I. From a growing concern with industrial accidents in the 1880s through the shell shock "epidemic" of the war, male hysteria seemed to bespeak the failings of German masculinity. In response, psychiatrists struggled to turn male-hysterical bodies into fit workers and loyal political subjects.

Medical approaches to trauma valorized work and productivity as standards of male health, and psychiatric treatment—whether through hypnosis, electric current, or suggestion—concentrated on turning debilitated soldiers into symptom-free workers. These concerns endured through the Weimar period, as "nervous veterans" competed for disability compensation amid the republic's political crises and economic upheavals.

Hysterical Men shows how wartime psychiatry furthered the process of medical rationalization. Lerner views this not as a precursor to the brutalities of Nazi-era psychiatry, but rather as characteristic of a more general medicalized modernity. The author asserts, however, that psychiatry's continual skepticism toward trauma resonated powerfully with the radical right's celebration of war and violence and its supposedly salutary effects on men and nations.
