    Extractions: Ruska, Ernst August Friedrich Nìmecký fyzik, elektroinženýr a držitel Nobelovy ceny za fyziku pro rok 1986 za návrh prvního elektronového mikroskopu a dalších vylepšení tohoto zaøízení. O cenu se dìlí spolu s Gerdem Karlem Binnigem z Nìmecka a Heinrichem Rohrerem ze Švýcarska, kteøí cenu obdrželi za návrh vzorkovacího tunelového mikroskopu. Narodil se v Heidelbergu. V roce 1931 dostal titul elektroinženýr na universitì v Berlínì a o dva roky pozdìji také titul Ph.D. V roce 1937 pøijal místo v laboratoøích Siemens-Reiniger-Werke. Zùstal zde až do roku 1955, kdy se stal øeditelem Institutu pro elektronovou mikroskopii, který byl zøízen pøi Fritz Haberovì institutu. V téže dobì uèil jako profesor na Berlínské technice a to od roku 1957 až do roku 1972, kdy odešel do dùchodu. Pøed tím, než opustil ve tøicátých letech universitu v Berlinì, již pøispìl k vìdeckému poznání. Vìdìl, že elektrony mají vlnový charakter a vìøil, že je pùjde využít k podobným úèelùm jako svìtlo. Ruska doufal, že magnetické pole mùže ovlivnit svazek elektronù, pøípadnì ho zaostøit. Poté, co si všechny pøedpoklady ovìøil experimentálnì, zaèal vytváøet elektronový mikroskop. Ruska si uvìdomil, že zvìtšení elektronového mikroskopu bude mnohem vìtší než u jeho optického protìjšku, protože vlnové délky elektronù jsou mnohem kratší než vlnové délky viditelného svìtla. V 1932 Ruska a spolupracovníci, nìmecký fyzik Max Knoll (pod jehož vedením dostal doktorát) postavili první primitivní elektronový mikroskop. Pøestože to byl jen první pokus a mikroskop nebyl pøímo použitelný dokázal pozorované pøedmìty zvìtšit 400×.

    Extractions: German engineer Ernst Ruska designed and built the first electron microscope, a device that far surpassed previous resolution capabilities and allowed scientists to view things too small to be seen with a light microscope. He was awarded the Nobel Prize for Physics in 1986 for the feat, an honor he shared that year with Heinrich Rohrer and Gerd Binnig, who co-developed the scanning tunneling microscope. Born on December 25, 1906, in Heidelberg, Germany, Ruska was the son of an Asian studies professor and the fifth of seven children. Many of his closest relatives were academics and his parents believed that he too might follow such a path. He studied at the Technical University of Munich from 1925 to 1927 and then moved to Berlin to attend the Technical University located there. While still enrolled in school, Ruska began to lay the groundwork for the achievement that would be his legacy. Under the tutelage of Dr. Max Knoll, Ruska developed an interest in the idea of electron microscopy. Realizing that optical microscopes were limited by the wavelength of the light beams used to view a specimen, Ruska determined that since electrons have much shorter wavelengths than light, they could be used to obtain greater resolving power. In 1931, working closely with Knoll, Ruska built the first electron lens, an electromagnet that could focus a beam of electrons, as if it were light. Using several such lenses, he was able to construct a prototype of an electron microscope, though with only the ability to magnify a meager 17 times. Yet, he had proven that the task was possible and he continued to improve his design. By 1933, Ruska's electron microscope, termed a transmission microscope, was much more powerful. The instrument worked by passing electrons through a thin slice of the specimen to be studied, which were then deflected to a photographic film emulsion or projected onto a fluorescent screen, generating an image at high magnification. In fact, the device was capable of magnifying specimens up to 10 times more than a contemporary light microscope.

    Extractions: The Ernst Ruska Prize, the European Prize for Electron Microscopy This prize was instituted by the "Ernst Ruska Preis Förderverein" ( ERPV The Ernst Ruska Prize has been transformed into a European prize. Two prizes are awarded, one in the materials/optics field and one in the biomedical field. The rules governing the prize are as follows: Candidates for the prize can be proposed by: European Microscopy Societies a group of scientists an individual scientist Candidates must be European, or of European origin; non-European scientists who work or have worked in Europe for more than a year are also eligible. A candidate need not necessarily be a member of a European National Microscopical Society. Applications should contain a resume (CV); a list of publications; reprints of five publications that best support the candidature, the candidate should be the leading author of these publications; and an appraisal and justification written by the proposer. Proposals should be received at the Secretariat of the EMS before April 1st. The selection of two candidates should be ready on June 1st. Candidates will be evaluated by a jury, the members of which are selected by the "Ernst Ruska Preis Förderverein" and the EMS. The names of the members of the jury will be made public at the next European Microscopy Congress (EMC).
