    Antonie van Leeuwenhoek invents the microscope

    Antonie van Leeuwenhoek developed ways to make superior lenses by grinding and polishing a glass ball into a lens with a magnification of 270x.
  • Joseph Jackson Lister discovers that using weak lenses together at various distances provided clear magnification.

    Joseph Jackson Lister discovers that using weak lenses together at various distances provided clear magnification.

    Lister developed an "achromatic" lens which atoned a distortion called "chromatic aberration". The achromatic lens encouraged scientists to accept the microscope as a reliable tool for medical research.
  • Richard Zsigmondy invents the unltramicroscope.

    Richard Zsigmondy invents the unltramicroscope.

    The advancement of the microscope to the ultramicroscope allowed observation of specimens below the wavelength of light.
  • Frits Xernike invents the phase-contrast microscope.

    Frits Xernike invents the phase-contrast microscope.

    With Frits Xernike's invention of the phase-contrast microscope, transparent biological materials are studied for the first time.
  • Ernst Ruska invents the electron microscope.

    Ernst Ruska invents the electron microscope.

    Just six years after the invention of the phase-contrast microscope comes the electron microscope,developed by Ruska, who realized that using electrons in microscopy enhanced resolution.
  • Gerd Binnig and Heinrich Rohrer invents the scanning tunneling microscope.

    Gerd Binnig and Heinrich Rohrer invents the scanning tunneling microscope.

    Binnig and Rohrer were recognized for developing the powerful microscopy technique that forms an image of individual atoms on a metal or semiconductor surface by scanning the tip of a needle over the surface at a height of only a few atomic diameters.
