Martin Julian Buerger (April 8, 1903 – February 26, 1986) was an American crystallographer. He was a Professor of Mineralogy at the Massachusetts Institute of Technology. He invented the X-ray precession camera for studies in crystallography. Buerger authored twelve textbooks/monographs and over 200 technical articles. He was awarded the Arthur L. Day Medal by the Geological Society of America in 1951. The mineral fluor-buergerite was named for him. The MJ Buerger Award (established by the American Crystallographic Association) was established in his honor. Buerger was a member of the Provisional International Crystallographic Committee chaired by P. P. Ewald from 1946 to 1948, and he continued as a member of the IUCr Executive Committee from 1948 to 1951. He was also a member of the Commission on International Tables from its establishment in 1948 until 1981. In 1956, Buerger was the third person (after John C. Slater and Francis O. Schmitt) to have been appointed Institute Professor at MIT. Significant works Crystal-Structure Analysis, 668pp, Krieger Pub Co., 1979 Introduction to crystal geometry, 204pp., R. E.
