First commercial Electron microscope, constructed by Ernst Ruska in 1939. Ernst August Friedrich Ruska (German pronunciation: [ɛʁnst ˈʁʊskaː] ⓘ; 25 December 1906 – 27 May 1988) [1] was a German physicist who won the Nobel Prize in Physics in 1986 for his work in electron optics, including the design of the first electron microscope.
Max Knoll (17 July 1897 – 6 November 1969) [1] was a German electrical engineer and co-inventor of the electron microscope.Knoll was born in Wiesbaden and studied at the University of Munich and at the Technischen Hochschulen in Munich and Berlin-Charlottenburg, where he obtained his doctorate in the Institute for High Voltage Technology.
Reproduction of an early electron microscope constructed by Ernst Ruska in the 1930s. Many developments laid the groundwork of the electron optics used in microscopes. [2] One significant step was the work of Hertz in 1883 [3] who made a cathode-ray tube with electrostatic and magnetic deflection, demonstrating manipulation of the direction of an electron beam.
Laboratory annexe to the ER-C inaugurated on 29 September 2011 housing the PICO together with four other electron microscopes. The ER-C develops new methods and technologies in the field of electron microscopy, with a special focus on ultra-high-resolution techniques to study solid state materials, soft materials and biological systems.
In 1931, Ernst Ruska (1986 Nobel Prize award winner) and Max Knoll created the first electron microscope. This invention led to the scanning electron microscope and transmission electron microscope, which later contributed to immunoelectron microscopy.
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).
