A fascinating look at German contributions to the study of cancer. Nazi doctors are known for the cruel human experiments they conducted on concentration camp inmates, their euthanasia program, and their willing participation in the selection process at the death camps. Proctor (History of Science/Pennsylvania State Univ.) detailed some of this hideous behavior a decade ago in Racial Hygiene (1988). Here, he makes a major contribution to our knowledge of the other side of Nazi medicine, the study of disease. Proctor’s account is well-researched and richly illustrated, and he delineates carefully documented facts in fluid prose. But the book is marred by an unclear argument exemplified by its deceiving title. Its actual subject is German research surrounding the cause, prevention, and cure of cancer, not just under the Nazis, but from the late 19th century through the early Cold War period. This includes the leading role German scientists played in diagnosing and fighting occupational hazards that caused cancer, in particular the proof they marshaled in the 1940s that smoking cigarettes caused lung cancer. Efforts to improve health through bans on smoking and alcohol were encouraged in the more racially and hygienically conscious circles of the Nazi hierarchy, especially the SS. Yet war shortages and stress led many Germans at home and at the front to booze it up and fill their lungs with smoke; Proctor never explains sufficiently why a health-obsessed totalitarian regime so seemingly effective in policing its citizenry allowed its Volk to indulge in liquor and cigarettes. He only vaguely touches on the complex nature of life under Nazism (explored by many scholars during the past two decades) and ventures onto shaky ground when discussing the relation of medical researchers to the greater society. Despite its shortcomings, an important, instructive book that expands our knowledge of the role medical researchers played in Hitler’s Germany. (39 b&w illustrations)
