Johannes Bednorz

A man with light brown hair and glasses, wearing a white lab coat over a blue checkered shirt, is depicted in the image.

A German physicist who, alongside Karl Müller at an IBM laboratory in Zurich, discovered high-temperature superconductivity in a barium-lanthanum copper oxide ceramic. Prior to their 1986 discovery, ceramics were considered strictly insulators. Their breakthrough triggered a global race to find materials that superconduct above the boiling point of liquid nitrogen, earning them the 1987 Nobel Prize in Physics.
