About Carl H. Hermann
Carl Heinrich Hermann, also spelled Karl Hermann, was a German physicist, crystallographer, and resistance fighter in Nazi Germany. He is known for his research in crystallographic symmetry, nomenclature, and mathematical crystallography in N-dimensional spaces. Hermann was a pioneer in crystallographic databases and, along with Paul Peter Ewald, published the first volume of the influential Strukturbericht (Structure Report) in 1931. During his Stuttgart years, Hermann also developed the first description of anisotropic properties of materials from a crystallographic perspective. The symmetry notation introduced by Hermann and Charles-Victor Mauguin, which later became an international standard notation for crystallographic groups known as the Hermann–Mauguin notation or International notation.
