Hans Busch (physicist)
From Infogalactic: the planetary knowledge core
Hans Busch (27 February 1884 in Jüchen, North Rhine-Westphalia, Germany – 16 February 1973 in Darmstadt, Hesse) was a German physicist. He was a pioneer of electron optics and laid the theoretical basis for the electron microscope.
Ernst Ruska read a paper by Busch in the academic journal Archives Elektrotechnik where Busch suggested that magnetic fields could be used to direct beams of electrons in a way analogous to the way lenses directed light in an optical microscope.[1]
In recognition of his work in the field, Busch was unanimously elected an honorary fellow of the German Society for Electron Microscopy at its first meeting in 1949.[2]
