"We replaced the wave length of the light by the wave length of electrons at an accelerating voltage of 75 kV and inserted into the Abbe relation the imaging accelerating voltage of 75 kV and inserted into the Abbe relation the imaging accelerating voltage of 75 kV and inserted into the Abbe relation the imaging aperture of 2 X 10-2 rad...we came up with a resolution limit of 2.2 Å ."
"Nevertheless, this certainly was the cheapest electron microscope ever paid for by a German organization for the promotion of science. "
"The most important thing in science is to be together with a colleague at that moment when you discover something. When some little piece of nature unfolds and you see something new. "
"Suppose you lived in a world in which the ground was a crossword puzzle. Would you or would you not try to solve the puzzle?""
"Frankly most of the stuff we try just doesn't work"
"I thought that if I patented it, no one else would be able to do work with it. I might earn some money, but I was not interested in that. I was interested in applications for many researchers, creating more fundamental science. So I decided not to patent it."
"As many of his colleagues can attest, the wave nature of the electron was no remote or discouragingly abstract conception to him. Peering at the viewing screen while he manipulated the controls of an electron microscope, he could be seen to be thinking in terms of wave functions. "
"Our century has seen the creation of new means of doing research. In particular, the electron microscope and chemical and biochemical methods of analysis have revolutionized our knowledge of the foundations of life..."
