“…The most far-reaching practical studies of the correcting capacity of a thin conducting foil placed in the path of an electron beam are those of Maruse, Ichihashi, Hibino and others in the University of Nagoya. Their progress and successes are charted in the following papers: Maruse et al (1970a,b), Ichihashi & Maruse (1971, Hibino & Maruse (1976), Hibino et al (1977Hibino et al ( , 1978Hibino et al ( , 1981Hibino et al ( , 1998, Hanai et al (1982Hanai et al ( , 1984Hanai et al ( , 1994Hanai et al ( , 1995Hanai et al ( , 1998 and Matsuda et al (2005).

Electron lenses are extremely poor: if glass lenses were as bad, we should see as well with the naked eye as with a microscope! The demonstration by Otto Scherzer in 1936 that skilful lens design could never eliminate the spherical and chromatic aberrations of rotationally symmetric electron lenses was therefore most unwelcome and the other great electron optician of those years, Walter Glaser, never ceased striving to find a loophole in Scherzer's proof. In the wartime and early post-war years, the first proposals for correcting C s were made and in 1947, in a second milestone paper, Scherzer listed these and other ways of correcting lenses; soon after, Dennis Gabor invented holography for the same purpose. These approaches will be briefly summarized and the work that led to the successful implementation of quadupole-octopole and sextupole correctors in the 1990s will be analysed. In conclusion, the elegant role of image algebra in describing image formation and processing and, above all, in developing new methods will be mentioned.
