In a few years' time, the electron microscope will be 100 years old. The ideas leading to the invention of the instrument emerged in Berlin between 1928 and 1933. Ernst Ruska is the undisputed.
Max Knoll and Ernst Ruska Electron Microscope YouTube
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. This means that only one hundredth - thousandth of a wavelength speeds the electrons making them move very fast.

Other articles where Knoll, Max is discussed: electron microscope: History:.by 1931 German electrical engineers Max Knoll and Ernst Ruska had devised a two-lens electron microscope that produced images of the electron source. In 1933 a primitive electron microscope was built that imaged a specimen rather than the electron source, and in 1935 Knoll produced a scanned image of a…

The optical microscope changed the science field forever. German physicist Ernst ruska and The
In fact, Ernst Ruska and Max Knoll, his supervisor, had designed, constructed, and exhibited a prototype electron microscope in Berlin in 193 1, well before the acceptance date of the patent, and so, under German law, were co-users of the patent. Unfortunately, Knoll died in 1969, so ajoint Knoll-Ruska award of the Nobel Prize was not possible..
Ernst Ruska Electron Microscope
By 1931, Max Knoll had became more and more involved in completing his habilitation treatise, and Ernst Ruska and Bodo von Borries began a close cooperation in designing and constructing electromagnetic lenses suitable for focusing a beam of electrons in a cathode ray oscillograph (von Borries & Ruska, E. 1932).

First Electron Microscope 1931
The electron microscope, which was invented by Ernst Ruska and Max Knoll in 1933, made it possible to take pictures of much smaller objects than was previously possible. Ernst Ruska's brother, Helmut Ruska, was a doctor and biologist, and used early electron microscopes to make images of viruses and other small objects.
On March 3, 1931, German physicist Ernst Ruska together with his doctoral advisor Max Knoll
Matter-wave microscopy can be dated back to 1932 when Max Knoll and Ernst Ruska published the first image obtained with a beam of focussed electrons. In this paper a new step in the development of matter-wave microscopy is presented. We have created an instrument where a focussed beam of neutral, ground-state atoms (helium) is used to image a.

Max Koll and Ernst Ruska. German engineer and Nobel Peace Prize winner, Ernst Ruska designed and built the first electron microscope which allowed scientists to view things that were too small to be viewed by the light microscope. In 1931, Ruska, began to work closely with fellow German Max Knoll to co-invent the first electron lens, an.
