Ernst Ruska was born in Heidelberg, Germany. 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 wavelengths 1000 times 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 demonstrated that a magnetic coil could act as an electron lens, and used several coils in a series to build the first electron microscope in 1933.
After completing his PhD in 1933, Ruska continued to work in the field of electron optics, first at Fernseh Ltd in Berlin-Zehlendorf, and then from 1937 at Siemens-Reiniger-Werke AG. At Siemens, he was involved in developing the first commercially produced electron microscope in 1939. As well as developing the Technology of electron microscopy while at Siemens, Ruska also worked at other scientific institutions, and encouraged Siemens to set up a laboratory for visiting researchers, which was initially headed by Ruska's brother Helmut, a medical Doctor who developed the use of the electron microscope for medical and biological applications.
In 1960 he won the Lasker Award. In 1986, he was awarded 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. He died in West Berlin in 1988.
