“Troubled times” seems a bland summary of the interwar years, and experts—statisticians, scientists and doctors—rather than individual or collective sufferers are “facing illness” in this volume. That said, this is an informative collection with a comprehensive introduction worth further expansion. The editors highlight the ambiguities surrounding health as a public issue in this period, with the repositioning of voluntary and charitable effort and increasing state involvement suggesting responsibility for individuals but exercising authority over them. Health matters took on greater significance in the formation and conceptualization of nations; integrating or excluding, helping to define borders and to forge identities. They were the focus of new and influential international bodies (notably the League of Nations Health Organisation, and the Rockefeller Foundation) and of scientific expertise, with developments in bacteriology, nutrition, eugenics, and social medicine interacting with contending political viewpoints. A healthy citizenry featured in varied ideologies offering “the promise of empowerment and uplift which included the option not only of a new position for the common man but of a new man per se, strengthened by improved education and status and significantly improved health” (p. 7). Differing interpretations of health, seen here as “neither an objective reality, nor a cultural construction but a synthesis of both” (p. 8), require allowance for conceptualization and contextualization by contemporaries and by historians. This involves the interaction of problem-laden objectification of certain “realities” and of their political, social or ideological usage. Most contributors are content to focus upon data or policy issues, however, and the book divides along these lines. Part One needed a summary of changes in mortality in European countries, as this cannot be established from individual chapters. Robert Lee's examination of causes of mortality, specifically defects in the quality of data and the limited implementation of an international classification system, demonstrates that “more” did not necessarily mean “better” in data provision. Mortality is a poor approximation for health and Paul Weindling reviews studies based on insurance, school and family records, and efforts to quantify morbidity and to utilize health indicators. Iris Borowy also evaluates problems surrounding the compilation and use of the League of Nations' International Health Yearbooks (1924–9) for comparative purposes. Central and south-eastern Europe, where health featured strongly in nation building, are well-represented. Hana Masova and Petr Svobodný survey health care in the new Czechoslovak Republic and the awkward combination of public health arrangements, an established sickness insurance scheme, and voluntary and state institutions with interests in social medicine. They see inclusionary innovations in social hygiene (combating “civilisation diseases”) and hospital provision before the Munich Agreement and subsequent invasion. Yugoslavia suggests contrasting interpretations. Željko Dugac focuses upon Andrija Stampar, at the Ministry of Health and working closely with the Rockefeller Foundation, who ascribed a pivotal role to public health and health education but was removed in 1931 by self-interested private physicians and ethnically-motivated anti-centralisers. Patrick Zylberman's study of the anti-malarial campaign in Macedonia depicts this as a form of border consolidation and “Serbianisation”, whereas Esteban Rodriguez-Ocana's parallel Spanish study suggests the limitations of international bodies and new medical technologies when faced by suspicious local physicians and powerful, unsympathetic landowners. Thorsten Halling, Julia Schafer and Jorg Vogele consider German infant mortality in the contexts of the epidemiological transition and of attempts to measure “human capital” assets (or, on racial or eugenicist grounds, liabilities). Sylvelyn Hahner-Rombach's examination of depictions of TB sufferers as “anti-social” is germane to this, though her comparison of medicine and scientific discourse with earlier social labelling of such “threats” seems compartmentalized. A disturbing parallel may lurk in the influence of Zionist ideology and the medical selection of Jewish migrants to Palestine, discussed by Nadav Davidovitch and Shifra Shvarts. Generally the approach is “top-downwards” in national or local studies, with some privileging of doctors, scientists or institutions as principal actors shaping health policy or medical campaigns (Lion Murard on Jaques Parisot in Nancy or Emilio Quevedo on the Rockefeller Foundation and the London School of Hygiene and Tropical Medicine). However Martin Gorsky and Bernard Harris build on James Riley's work, using Hampshire Friendly Society records to suggest that rising claim rates were driven by an ageing population, specifically the over-fifties. This offers a rare glimpse of ordinary people facing illness in a none the less valuable and informative collection.
