...a device that uses electrons instead of light and electron lenses instead of optical lenses to create a magnified image of an object. In 1926, H. Busch of the University of Jena in Germany published the theory of the electron lens. Based on this theory, E. Ruska and his mentor M. Knoll created the world's first electron microscope at the Technical University of Berlin in 1932, combining an electron source and an electron lens. In 1939, the first commercial electron microscope was released to the world by the German company Siemens. *Some of the terminology references "Busch, Hans" are listed below.
