Was the electron microscope invented in Germany?
Yes. German engineers Ernst Ruska and Max Knoll built the first machine in 1931 in Germany. It didn't outperform the best optical microscopes, but it served to demonstrate the ideas. A couple of years later, Ernst Ruska (working for Siemens in one of their German locations) built an electron microscope that surpassed the resolution limits of an optical microscope. Wikipedia has a nice article on the history of the electron microscope, and a link is provided to that post. You'll find it below.

Who invented the electron microscope?
German physist Ernst Bruche invented it with the help of his assistant, Ernst Ruska. Sadly, his assistant betrayed him, and went to work for someone else. Ernst Ruska got the Nobel Prize for his invention, but it should have belonged to Ernst Bruche. Some Electron Microscope History: It is widely accepted that the first PROTOTYPE of an electron microscope was built by Ernst Ruska and Max Knoll in 1931; it was not more powerful than an optical microscope, but it demonstrated the principle that is still used in today's sophisticated and powerful instruments, and earned its builders a share of a Nobel Prize. In 1933, Ruska built a a new prototype instrument that was more powerful than any optical microscope, but still just an experimental instrument. The first PRACTICAL electron microscope was not constructed until 1938, by Eli F Burton of the University of Toronto along with students Cecil Hall, James Hillier and Albert Prebus. There does not seem to be any literature linking Ernst Ruska to Ernst Bruche, nor any literature relating any claim by Bruche to developmental work on the electron microscope. Some bibliography is going to have to be provided in order for the sad tale of Ruska betraying Bruche to be credible.

How is electron microscopy a useful tool in the study of cell structure?
Richard t Electron microscope is a very special tool which uses electron beam and invented by knoll and ruska which classified as transmission electron microscope uses 2d electron beam which clearly seen the internal structure of the cell and scanner electron microscope uses 3d electron beam which sweeps over the specimen.So it is very powerful with 5000 magnification of the object than a simple microscope.
