Electron microscopes, first developed in the nineteen thirties, opened an entirely new frontier by surpassing the limits of light based imaging. Their powerful beams allowed scientists to observe viruses, cell structures, and materials at previously unreachable scales. By the nineteen fifties and sixties, these instruments reshaped research in biology, medicine, and materials science, revealing intricate architectures that transformed human understanding of the microscopic world.
