  • Max Knoll

    Invention of the electron microscope.
  • Gerd Binning

    Invented the scanning tunneling microscopes that give three dimensional images of objects down to the atomic level.

  • Hirox Co Ltd.

    Invented and developed the first digital microscope by adding a function that translated the visual image into a digital picture.
  • Leo Szilard

    Created the first atomic bomb.
  • Robert Remak

    Dsicovered and renamed the three germ layers of the early embryo.
