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.
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.
Albert Victor Crewe (February 18, 1927 – November 18, 2009) was a British-born American physicist and inventor of the modern scanning transmission electron microscope [1] capable of taking still and motion pictures of atoms, a technology that provided new insights into atomic interaction and enabled significant advances in and had wide-reaching implications for the biomedical, semiconductor ...
He took out approximately 600 patents in fields including electron microscopy, medical technology, nuclear technology, plasma physics, and radio and television technology. From 1928 to 1945, he directed his self-funded and private research laboratory Forschungslaboratorium für Elektronenphysik , where he developed and invented many techniques ...
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).
Eli Franklin Burton OBE, FRSC (February 14, 1879 – July 6, 1948) was a Canadian physicist.. Burton was born in Green River, township of Pickering, Ontario, Canada.He graduated from the University of Toronto in 1901.
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.
Erwin Wilhelm Müller (or Mueller) (June 13, 1911 – May 17, 1977) was a German physicist who invented the Field Emission Electron Microscope (FEEM), the Field Ion Microscope (FIM), and the Atom-Probe Field Ion Microscope. He and his student, Kanwar Bahadur, were the first people to experimentally observe atoms. [1]
