Boundaries, Transformations, Historiography: Physics in Chemistry from the 1920s to the 1960s

The decades of the 1920s to the 1960s were a period of transformation in chemical science. The era was marked by erosion of boundaries that had often been drawn between chemistry and other scientific disciplines. In particular, theories, instruments, and mathematical approaches associated with the new physics of X-rays, the electron particle, and the electron wave enabled chemists and other physical scientists to address unsolved chemical problems of structure and mechanism and to ask new questions that further expanded and transcended disciplinary borders. In turn, the historiography of these developments reflects the pluralism of chemistry in historical narratives written by scientists, historians, philosophers, and sociologists.
