Max von Laue (October 9, 1879 - April 24, 1960) was a German physicist, who studied under Max Planck. From 1919 he was professor of theoretical physics at the University of Berlin. He worked out a method for measuring X-ray wavelengths, in which a crystal (e.g. rock salt) is used, producing diffraction of the rays. For this work, which also made possible a closer study of crystal structure (a method called X-ray crystallography), he received the 1914 Nobel Prize in Physics.
