Heinrich Rohrer

The 1986 Nobel Prize in Physics is being recalled for recognising electron microscopy and scanning tunnelling microscopy, technologies that use electrons instead of light to image matter down to individual atoms. Ernst Ruska received half the prize for developing the electron microscope, while Gerd Binnig and Heinrich Rohrer shared the rest for the scanning tunnelling microscope at IBM Zurich, work that transformed nanoscience and materials research.
