Over the years, I have read with great interest several articles and book chapters about historical aspects of electron microscopy. The report by F. Haguenau et al. about the key events in the history of electron microscopy (Microscopy and Microanalysis, Vol. 9, No. 2, April 2003, pp. 96–138) is, to my knowledge, by far the most comprehensive article ever published. The authors did a superb job in first listing chronologically the development of electron optics and instrumentation for the years from 1897 to 2002, and then describing major applications in physics and materials science, as well as life sciences.
