The electron microscope was conceived and built in the Technical University of Berlin some 50 years ago. Much of its further development took place in university laboratories. Some significant contributions came to be made in the Cavendish is respect of high voltage operation and the improvement of resolution, and in microanalytical instrumentation.
Part I (Vol. 22, no. (1), pp. 3-36), covering the years, 1946-60, included some account of the prehistory of he subject, the exploration of the operation and applications of the first commercial models, the development of an X-ray microscope and, from it, the scanning microprobe analyzer Part II now continues the story, through the two following decades, the conception and construction of a high voltage electron microscope, and then its extension to an instrument capable of atomic resolution.
