The impact of British chemistry and physics upon Japanese science in the late nineteenth century: the Williamson-Sakurai connection at University College London

The Meiji period between 1868 and 1912, when the introduction of Western science into Japan started in earnest, was also the time when specialization became an increasingly pressing and complex issue in natural science, especially in Victorian Britain where specialization went hand in hand with 'interconnectedness' between various fields of study. This article examines the impact of this complicated situation surrounding 'specialization' in nineteenth-century British science on Meiji Japan, taking chemistry and physics (natural philosophy) teaching at University College London (UCL) in the 1870s as an example. It reveals how chemistry and physics became interconnected with each other in UCL's science education by the presence of its chemistry professor, Alexander William Williamson (1824-1904), and the impact of this connection on Japanese science with a focus on Williamson's Japanese student, Sakurai Joji. This paper argues that the interconnectedness of UCL's chemistry and physics significantly affected the disciplinary identity of the Department of Chemistry at the Imperial University of Tokyo through Sakurai.
