Gerd Binnig

Gerd Binnig (born 20 July 1947) is a German physicist renowned for his pioneering contributions to nanotechnology, particularly as the co-inventor of the scanning tunneling microscope (STM) in 1981 and the atomic force microscope (AFM) in 1986, instruments that revolutionized the ability to image and manipulate matter at the atomic scale. For the STM, he shared the 1986 Nobel Prize in Physics with Heinrich Rohrer and Ernst Ruska, recognizing the breakthrough in electron microscopy that enabled direct observation of individual atoms. His work at IBM's Zurich Research Laboratory laid the foundation for modern scanning probe microscopy, earning him additional accolades including the German Physics Prize, the Hewlett-Packard Europhysics Prize, the King Faisal International Prize, and the 2016 Kavli Prize in Nanoscience for the AFM, shared with Christoph Gerber and Calvin F. Quate.

Born in Frankfurt am Main, West Germany, Binnig grew up in a post-World War II environment that shaped his early interest in science and technology, though he initially pursued diverse hobbies including music and sports. He earned his diploma and PhD in physics from Goethe University Frankfurt in 1973 and 1978, respectively, under the supervision of Werner Martienssen, focusing on topics in solid-state physics. In 1978, he joined IBM Zurich Research Laboratory, where he collaborated closely with Rohrer, Christoph Gerber, and others to develop the STM—a device using quantum tunneling effects to scan surfaces with atomic resolution—overcoming the limitations of conventional optical and electron microscopes. This innovation not only earned the Nobel but also spurred applications in materials science, chemistry, and biology.
