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.
It was inaugurated on 18 May 2006 in the presence of members of the Ernst Ruska family, as well as representatives of the international electron microscopy community. [2] On 1 January 2017, the ER-C attained the status of an independent scientific institute in Forschungszentrum Jülich.
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.
In 1927 he became the leader of the electron research group there, where he and his co-worker, Ernst Ruska, invented the electron microscope in 1931. [2] [3] In April 1932, Knoll joined Telefunken in Berlin to do developmental work in the field of television design. He was also a private lecturer in Berlin. [citation needed]
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).
Ernst Ruska was the inventor of the electron microscope, and later winner of a Nobel Prize. From 1948 to 1951, Helmut Ruska was a professor at the University of Berlin, in 1952 he moved to the United States where he was a micromorphologist for the New York State Department of Health in Albany.
In 2004, the Ernst Ruska-Centre for Electron Microscopy was founded. It is equipped with transmission electron microscopes. Soil and environmental research were interlinked with climate research. In 2001, the SAPHIR atmospheric simulation chamber was inaugurated, followed by the PhyTec experimental facility for plants in 2014.
Born in Brantford, Ontario, the son of James and Ethel (Cooke) Hillier, he received a Bachelor of Arts in Mathematics and Physics (1937), Master of Arts (1938), and a Ph.D (1941) from the University of Toronto, where, as a graduate student, he completed a prototype of the electron microscope that had been invented by Ernst Ruska.
