The 1914 Nobel Prize in Physics recognized the diffraction of X-rays by crystals, a fundamental discovery that transformed the study of atomic structures. Max von Laue achieved this breakthrough during his time in Munich, effectively launching the field of X-ray crystallography and establishing the mathematical relationship now known as the Laue equations.
Academic Foundations and Early Research
Born in Koblenz in 1879, Max von Laue pursued an extensive scientific education across Germany, including studies at the University of Strasbourg, the University of Göttingen, and the Ludwig-Maximilians-Universität München. By 1903, he had completed his Ph.D. at the Friedrich Wilhelm University of Berlin, where he worked under Max Planck. His early investigations centered on optics, quantum theory, and the application of entropy to radiation fields. During his tenure as a Privatdozent at the University of Berlin, he established a lasting friendship with Albert Einstein, actively contributing to the early acceptance of the theory of relativity.

Take the IQ test →The X-Ray Diffraction Discovery
In 1912, while working in Munich, Laue proposed that the periodic arrangement of atoms in a crystal might act as a diffraction grating for X-rays, which possess wavelengths comparable to interatomic distances. Collaborating with Paul Knipping and Walter Friedrich, he experimentally confirmed this hypothesis. This work provided the first direct evidence of the wave nature of X-rays and enabled the determination of internal crystal structures, forming the basis for subsequent advancements in crystallography.
Institutional Leadership and Superconductivity
Laue held professorships at the University of Zurich, the University of Frankfurt am Main, and the University of Berlin. As a trustee and deputy director of the Kaiser Wilhelm Institute for Physics in Berlin-Dahlem, he managed critical administrative and scientific functions. His research interests expanded into the study of superconductivity, where he analyzed magnetic field decay in superconductors, often working alongside Walther Meissner to describe how applied magnetic fields affect superconductive states.
Opposition to Political Interference
Throughout the 1930s, Laue openly defied the rise of Nazism and the efforts to suppress modern physics under the banner of Deutsche Physik. He particularly resisted the branding of relativity as ideologically unacceptable. By assisting colleagues targeted by the regime and refusing to align with political mandates, he faced repeated government reprimands. Following the Second World War, he played a central role in the reorganization of German scientific institutions.
