Abstract
Knoll and Ruska developed the first electron microscope during their research to improve the demountable high-voltage cathode-ray oscillograph. Starting with the investigation of the well-known focusing coil, they progressed step by step until, in 1933, Ruska could show the first pictures with resolutions beyond those obtainable with an optical microscope. Rein-hold Rudenberg is sometimes called the inventor of the electron microscope because he was the first to apply for patents on it. Actually, he did not contribute to the development of the first microscope. When he filed his first patent applications, Knoll and Ruska had already built the first model and had shown it to many interested people (35).Keywords
