This paper aims to shed new light on the post-WWII history of blood groups and race, illuminating the postcolonial revitalization of racial serology in South Korea. In the prewar period, Japanese serologists developed a serological anthro- pology of Koreans in tandem with Japanese colonialism. The pioneering Korean hematologist Yi Samyŏl (1926–2015), inspired by decolonization movements during the 1960s, excavated and appropriated colo- nial serological anthropology to prove Koreans as biologically independent from the Japanese. However, his racial serology of Koreans shared colonial racism with Japanese anthropology, despite his anti-colonial nationalism. Keywords: race; blood groups; racial serology; decolonization movements; scientific nationalism; South Korea Introduction In 1969, prominent South Korean hematologist Yi Samyŏl(李三悅, 1926–2015) published an article on blood-group research to prove Koreans’“blood purity” (純血) and to contend “scientific independence” (科學的自主性) (Yi 1969, 57).1 In this paper, he surveyed the blood-group dis- tribution of Koreans, including state-of-the-art blood-group systems like the Diego antigen system.2 Based on his intensive research, Yi proudly claimed, “Koreans are a racially homogeneous nation (單一民族) and have not been mixed with the blood of neighboring ethnic groups,” while the Chinese and the Japanese were “a mongrel race (雜種) whose blood is mixed” or “a racially mixed nation” (混合民族) (ibid., 64).3 At the same time, Yi contended that Korean scientists would have to achieve scientific independence from Japan and the United States in order to estab- lish Koreans as biologically independent from the Japanese.
