Max Knoll and Ernst Ruska - The Microscope
WebErnst Ruska & Max Knoll Co-Founders Ernst Ruska and Max Knoll (German) won half of the nobel prize in physics in 1986 for this invention. In this type of microscope, a vacuum speeds up all the electrons forcing their wavelength to be very short. On March 9, 1931, German physicist Ernst Ruska together with his doctoral advisor Max Knoll presented the very first prototype electron microscope, capable of four-hundred-power magnification; the apparatus was the first demonstration of the principles of electron microscopy. “The light microscope … See more Ernst Ruska was born on 25 December 1906 in Heidelberg as the fifth of seven children of Julius Ruska, professor of oriental studies, and his wife Elisabeth Ruska, née Merx. … See more Under the direct tutelage of Dr. Max Knoll and together with other doctoral students Ernst Ruska worked on the development of a high performance cathode ray oscilloscope.
