Ernest Ruska

Ernest Ruska was a German physicist who pioneered the development of the electron microscope, an advanced tool that uses electron beams instead of light to see extremely small objects. His innovations allowed scientists to observe details at the atomic and molecular levels, greatly advancing fields like materials science and biology. Ruska’s work earned him the Nobel Prize in Physics in 1986, shared with others, for helping improve these powerful microscopes. His contributions significantly transformed microscopy, enabling us to explore the fundamental structures of matter with unprecedented clarity.
