Werner Fischer (born February 8, 1931, in Gablonz an der Neisse, Czechoslovakia) is a German mineralogist and mathematical crystallographer.
There he also received his doctorate in 1959 with a thesis on structural studies on synthetic carnallite.
In 1970 he habilitated at Philipps-University Marburg with a thesis on homogeneous packing of spheres and their conditions of existence in space groups of tetragonal symmetry.
Fischer's research dealt with mathematical crystallography, in particular with periodic minimal surfaces, sphere packings, effective areas, normalizers,[1][2] lattice complexes,[3] the description of crystal structures and worked on the International Tables for Crystallography.
[4] Fischer received the 2006 Carl Hermann Medal from the German Crystallographic Society.
