Carl H. Hermann

Carl Heinrich Hermann (17 June 1898 – 12 September 1961), also spelled Karl Hermann (German:), 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.

In 1943, he and his wife were imprisoned by the Gestapo for harboring a Jewish family. They were honored with medals of the Righteous Among the Nations by Yad Vashem in 1976.
