History of Science and Technology of Electron Microscopy - Theoretical Progress and Instrumental Development -

主要研究了日本电子显微镜的早期历史和发展。日本电子显微镜特别是高压显微镜的成功发展与电子衍射和显微技术的理论发展密切相关。1939年为电子显微镜合成研究而成立的第10委员会日本科学促进会（JSPS）第37分科，聚集了相关研究人员。电子显微镜在日本的发展是由这个小组委员会的成员开始的。这些活动使日本公司在第二次世界大战后不久建立了商业化的机器，并完成了电子显微镜的第一次出口。相反，电子衍射的实验和理论工作的发展是由年轻的研究人员组织的电子衍射研究小组独立推动的。

Early history and development of electron microscopy in Japan has mainly been studied. Successful development of electron microscope, especially high voltage electron microscope in Japan was strongly correlated to theoretical progress of electron diffraction and microscopy. The 37th subcommittee of the 10th committee, Japan Society for the Promotion of Science (JSPS), was established in 1939 for the synthetic research on electron microscopy, where the concerned researchers were gathered. Development of electron microscopes in Japan was started by members of this subcommittee. Such activities were responsible for Japanese company to establish commercialized machines and accomplish the first export of an electron microscope soon after the Second World War. In contrast, the developments of experimental and theoretical works of electron diffraction were independently promoted by the study group of electron diffraction organized young researchers.
