Ruska was born in Heidelberg. He was educated at the Technical University of Munich from 1925 to 1927 and then entered the Technical University of Berlin, where he posited that microscopes using electrons, with waves 1,000 shorter than those of light, could provide a more detailed picture of an object than a microscope utilizing light, in which magnification is limited by the size of the wavelengths. In 1931, he built an electron lens and used several of these in a series to build the first electron microscope in 1933. For other uses, see Heidelberg (disambiguation). ...

Concurrently, Ruska served at the institute and as professor at the Technical University of Berlin, from 1957 until his retirement in 1972. In 1986, he won half of the Nobel Prize in Physics for his many achievements in electron optics; Gerd Binnig and Heinrich Rohrer won a quarter each for their design of the scanning tunneling microscope.

Full name: Ernst August Friedrich Ruska Date of birth: December 25 1906 Death: May 25 1988 he dies at age 81 Country where born: Heidelberg Germany


In the year 1933 Ernst invented the microscope. It let biologists see viruses and the structure inside the cells. A Electron microscope can magnify up to 100000x. Ernst was awarded the Nobel prize in the year 1986 but only 50% of the award belongs to him. The other 50% he shares with 2 other scientists. He received an engineering degree the same year he invented the Electron microscope.

Ernst Ruska Biography / Biography of Ernst Ruska Microbiology and Immunology Biography (869 words)
Ruska was born in Heidelberg, Germany, on December 25, 1906.
Ruska subsequently worked with the Siemens Company to produce for the commercial market an electron microscope with a resolution to one hundred angstroms (by contrast, modern electron microscopes have a resolution to one angstrom, or one ten-billionth of a meter).
Ruska's microscope--called a transmission microscope--captures on a fluorescent screen an image made by a focused beam of electrons passing through a thin slice of metalized material.
