Gerd Binnig

Gerd Karl Binnig was born in Germany on 20 July 1947. A physicist by training, he co-invented the scanning tunneling microscope with Heinrich Rohrer, a tool that let scientists map surfaces at the atomic scale for the first time. The work earned them the Nobel Prize in Physics in 1986. The microscope didn't rely on lenses or light — it measured quantum tunneling currents between a probe and a surface, turning invisible atomic landscapes into something human eyes could read.
