Ernst Ruska Biography Ernst Ruska, Nobel Prize Winner. 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. Dr. Ruska was a native of Germany and received his schooling at the Technical University of Berlin. In his life time Dr. Ruska recieved many awards for his development, and improvements on the electron microscope. He died in May of 1988 in West Berlin at the age of 81.

Ernst Ruska 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.

Ernst August Fridrich Ruska Ernst Ruska se narodil 25. prosince 1906 v Heidelbergu. Vystudoval elektrotechniku v Mnichovì a v Berlínì. Od roku 1928 se zajímal o problematiku magnetického pole, které je ovlivòováno elektrickým proudem. Snažil se využít vlnového charakteru elektronù a zkoušel ovlivnit svazek elektronù magnetickým polem a takto ho zaostøit. Po mnoha pokusech spolu s nìmeckým fyzikem Maxem Knollem sestrojil v roce 1931 elektronový mikroskop, který dosahoval 400 násobného zvìtšení. Vycházel pøitom pøedevším z prací teoretického fyzika a zakladatele vlnové mechaniky Louise de Broglie. Mnohem vìtší zvìtšení oproti mikroskopùm optickým spoèívá v tom, že vlnová délka elektronù je mnohem menší než vlnová délka viditelného záøení. Elektronové mikroskopy dosahují v souèasnosti zvìtšení více než 2 000 000x. Na konci 30. let 20. století již vznikly v Ústavu elektronové optiky elektronové mikroskopy, které byly plnì použitelné pro vìdeckou práci a byly urèeny k prodeji. Elektronový mikroskop se stal nepostradatelným pomocníkem v biologii, medicínì, fyzice, ke zkoumání struktury materiálù a v mnoha dalších vìdních obrech. Èinnost Ústavu, která byla bìhem války omezena, byla opìt obnovena už v roce 1945. V létech 1937 – 1955 pracoval Ernst Ruska v laboratoøích Siemens, kde se vyrábìl elektronový mikroskop Elmiskop 1 a který byl používán k vìdecké práci po celém svìtì. V roce 1955 byl jmenován øeditelem Institutu pro elektronovou mikroskopii pøi Fritz Haberovì institutu. V létech 1957 – 1972 vyuèoval na berlínské technice. V roce 1986 byla Ernstu Ruskovi spolu s Gerdem Karlem Binningem a Heinrichem Rohrerem udìlena Nobelova cena za fyziku za práce na poli elektronové optiky.
