   Extractions: Dr. Ruska was awarded the nobel prize in 1986 for his invention of the electron microscope. The electron microscope, which was built in 1931 uses electrons instead of light to veiw a specimen. This new instrument permitted biologists, for the first time, to veiw virusus and other detailed structures inside cells. Many of these new veiws were 1 million times more detailed than what was being seen by light microscopes.

    Extractions: He completed his first scientific work during 1929, which was concerned with the mathematical and experimental proof of Busch’s theory of the effect of the magnetic field of a coil of wire through which an electric current is passed and which is then used as an electron lens. Through this intensive study he recognized that focal length of waves could be shortened by the use of an iron cap, form this discovery the polschuh lens was developed, a lens used in all magnetic high-resolution electron microscopes. In 1931 he and Dr Knoll constructed the first electron microscope, with this instrument two of the most important processes for image reproduction were introduced- the principles of emission and radiation. In 1933, Ruska was able to put into use an electron microscope, that for the first time gave better definition than a light microscope. During his Doctoral thesis of 1934 and for his university teaching thesis (1944) at the Technical College in Berlin, he continued to investigate the properties of electron lenses with short focal lengths. Since further technical development of electron microscopes could not be financially supported by the university, Ruska went to work in the field of electron optics. From 1933-1937 he worked with Fernseh Ltd in Berlin-Zehlendorf and was responsible for the development of television receivers and transmitters, and well as photoelectric cells with secondary amplification. During this time he continued to develop a high-resolution electron microscope because he was convinced that is had great practical importance for applied and pure research.

Es beruhte auf der Tatsache, dass Magnetfelder Elektronen wegen ihrer Ladung ablenken können und sich Elektronenstrahlen in gleicher Weise bündeln und fokussieren lassen wie Lichtstrahlen durch Linsen . Da die Wellenlängen der Elektronen beträchtlich kürzer sind als diejenigen des Lichts, war das Elektronenmikroskop wesentlich wirksamer als ein optisches Mikroskop herkömmlicher Art. Ruska vervollkommnete seine Erfindung mit dem Ingenieur Bodo von Borries , sodass es 1938/39 serienmäßig hergestellt werden konnte. 1986 erhielt Ruska mit

    Extractions: In the years following 1945 I, together with a majority of new colleagues, reconstituted the Institute of Electron Optics in Berlin-Siemensstadt, which had been disbanded due to bombing, so that by 1949 electron microscopes were again being built. This new period of development led in 1954 to 'Elmiskop 1', which since then has been used in over 1200 institutions the world over. At the same time I sought the further physical development of the electron microscope by working at other scientific institutions. Thus from August 1947 to December 1948 I worked at the German Academy of Sciences in Berlin-Buch in the Faculty of Medicine and Biology, then from January 1949 as Head of Department at what is today the Fritz Haber Institute of the Max Planck Society in Berlin-Dahlem. Here on 27 June 1957 I was made Director of the Institute for Electron Microscopy, after I had given up my position with Siemens in 1955. I retired on 31 December 1974. From 1949 until 1971 I held lectures on the basic principles of electron optics and electron microscopy at both the Free University and the Technical University of Berlin. My publications in the area of electron optics and electron microscopy include several contributions to books and over 100 original scientific papers.

May 27, 1988, West Berlin), German electrical engineer who invented the electron microscope . He was awarded half of the Nobel Prize for Physics in 1986 (the other half was divided between Heinrich Rohrer and Gerd Binnig Ruska studied at the Technical University of Munich during 1925-27 and then enrolled at the Technical University in Berlin. Around this time he began the studies that led to his invention of the electron microscope. The extent to which an optical microscope could resolve the detail of a highly magnified object was limited by the wavelengths of the light beams used to view the object. Since it had been established in the 1920s that electrons have the properties of waves about 100,000 times shorter than those of light, Ruska posited that if electrons could be focused on an object the same way light is, at extremely high magnifications the electrons would yield greater detail ( i.e.
