Ernst Ruska

Ernst Ruska was a German physicist who played a crucial role in the development of the electron microscope, a powerful instrument that magnifies objects using electrons instead of light. This innovation, introduced in the 1930s, allowed scientists to see structures at the nanometer scale, far beyond the capabilities of traditional light microscopes. Ruska's work has had a profound impact on fields like biology and materials science, enabling advancements in our understanding of cells, viruses, and nanotechnology. For his significant contributions, he was awarded the Nobel Prize in Physics in 1986.
