Abstract
Does the molecular vision of life signify a unique revolution in biology or a more general evolution of the life sciences in the twentieth century? This paper visits this ‘big question’ by reflecting on a series of major debates in the historiography of molecular biology, especially those regarding its origins and the periodization of its development. For instance, while some have suggested that the discipline emerged in the 1930s, others have argued for its birth in the post-WWII era. Above all, the impact of the Rockefeller Foundation and the physical sciences on the formation of molecular biology remains a central topic of discussion among historians of biology. Unlike earlier historians of biomolecular science, recent scholars have also started to pay closer attention to the laboratory and material cultures that had conditioned its historical shaping. This paper argues that, ultimately, these debates all rest upon one fundamental historiographical problem: the absence of a unifying understanding of ‘molecular biology’ among historians (and practitioners) of biological science. This heterogeneous conceptualization of ‘molecular biology’, however, should be viewed as valuable because it allows for multiple approaches to resolving the ‘revolution versus evolution’ debate that together enrich our interpretation of the twentieth-century biomolecular vision of life
