Abstract
Manfred Pflanz, an internist with his focus on social medicine, medical sociology and epidemiology, (1923-1980) played a key role in the institutional integration of social science expertise into medicine in the Federal Republic of Germany during the 1960s and 70 s. The present study, a biographic sketch of Pflanz, describes his work, his programmatic ideas on social medicine and medical sociology, and his activities as an expert consultant in public health for various political entities. This should enable getting an insight into the origins and ramifications, as well as the contemporary programs and international embeddedness of the overlapping fields of social medicine and medical sociology in Germany.
