    The company of Carl Zeiss exploited this discovery and becomes the dominant microscope manufacturer of its era. 1928: Edward Hutchinson Synge publishes theory underlying the near-field scanning optical microscope; 1931: Max Knoll and Ernst Ruska start to build the first electron microscope. It is a transmission electron microscope (TEM).
