| About the name | Named in 1966 by Gaibriel Donnay, C. O. Ingamells, and Brian H. Mason, in honor of Martin Julian Buerger [April 8, 1903 Detroit, Michigan, USA - February 26, 1986 Lincoln, Massachusetts, USA], Professor of Mineralogy at the Massachusetts Institute of Technology and a pioneer of crystal structure analysis. He invented the X-ray precession camera permitting undistorted photography of the reciprocal lattice. He wrote many standard works concerning X-ray crystallography and was the PhD adviser for Harvard University mineralogist Clifford Frondel. It was renamed fluor-buergerite by Henry et al. (2011). |
