The article discusses the immediate post-war persistence and subsequent rejection of eugenics in East-Central European socialist states, exploring the case of premarital medical certificates. Building our analysis on published and archival sources, we show that immediately after the war, policies formulated at the governmental level were informed by eugenic ideas in medical expertise. Premarital medical certificates were aimed at combatting contagious diseases and thus securing a healthy population. Their legal status varied: in Poland, they were formally introduced; in the Soviet (...) Occupied Zone and East Germany, Nazi law was abolished, but local officials still advocated for the introduction of certificates; and in Czechoslovakia, medical certificates were planned but not introduced. Despite these differences, after a short period between 1949 and 1950, the attempts to put a measure into practice ended in all three countries. We argue that the communist takeover and consolidation of power played a decisive role. After 1950, premarital medical certificates were not discussed again in Czechoslovakia or East Germany; in Poland, the debate re-emerged in 1959–60 during political liberalization. (shrink)

This essay asks why Chinese and North Vietnamese agricultural scientists in the 1950s and 1960s willingly adopted the Soviet agricultural sciences represented not only by agronomists Ivan Michurin and Trofim Lysenko but soil scientist Vasili Williams. The answer, I argue, is that they were fascinated by the promise of Soviet agrobiology that I conceptualize as a combination of dialectical materialism and voluntarist productivism: if one masters the interconnectivity between plants, microbes, organic and inorganic materials, and soil, one can overcome the (...) given biological and environmental limits, manipulate and optimize the material flow, and ceaselessly maximize agricultural production. Engaging the historiographical debate about Lysenkoism—which has mostly paid attention to the Euro-American cases, genetic controversies, and geopolitical specificities of each locale—as a global phenomenon, I shed fresh light on the understudied Chinese and North Vietnamese cases, the intersection between Lysenko’s theories and Williamsian soil science, and epistemic commonality across national differences.
