… Near the middle of the 19th century, British mineralogist WH Miller established a notation for crystal systems and face indices based on symmetry (1839), and Frenchman A. Bravais completed the classification of space lattices by symmetry (1850). However, the difference between the heliomorphic and hemimorphic crystal families, which had already been known since Weiss's time, required the study of the symmetry of the crystal building blocks themselves, which are arranged according to the framework of the space lattice. German physicist L. Sohncke provided a partial answer to the symmetrical relationship between the space lattice and the building blocks, but at the end of the 19th century, the complete answer was given by the space group theory, which was independently constructed by three men: E.S.Fedorov of Russia, A.M.Schönflies of Germany, and W.Barlow of England, and thus classical crystallography was completed.

… 19世紀半ば近くになって,イギリスの鉱物学者ミラーW.H.Millerは対称の検討に基づいた結晶系と面指数の記号法とを確立し(1839),またフランスのA.ブラベは対称による空間格子の分類を完成した(1850)。しかしワイスの時代から既に知られていた完面像晶族と半面像晶族との差については,その理解には空間格子という枠に従って配列するところの結晶構成単位そのものの対称の研究が必要であり,この空間格子と構成単位との対称的な関係について,ドイツの物理学者ゾーンケL.Sohnckeがその一部に解答を与えたが,19世紀末にいたって,ロシアのフェドロフE.S.Fedorov,ドイツのシェーンフリースA.M.Schönflies,イギリスのバーローW.Barlowの3人によって互いに独立に建設された空間群論によって,その完全な解答が与えられ,ここにいたって古典的な結晶学が完成されたのである。【定永 両一】。…
