Alexei Vasilievich Shubnikov

Alexei Vasilievich Shubnikov (Алексей Васильевич Шубников; 29March 1887 – 27April 1970) was a Soviet crystallographer and mathematician. Shubnikov was the founding director of the Institute of Crystallography (named after him following his death) of the Academy of Sciences of the Soviet Union in Moscow. Shubnikov pioneered Russian crystallography and its application.

Career
In 1912 Shubnikov graduated from the Department of Natural Sciences of the Faculty of Physics and Mathematics of Moscow University. From 1920 to 1925 he was a professor at the Ural Mining Institute, Yekaterinburg. In 1925, at the invitation of the well-known mineralogist and geologist Alexander Fersman, he went to Leningrad, where he founded a laboratory of crystallography and laid the foundations of the Soviet school of theoretical and applied crystallography and related fields. From 1927 to 1929 he visited research institutions in Norway and Germany and worked temporarily with Friedrich Rinne. In 1934 he received a doctorate in the field of geological sciences. As part of a restructuring in the Academy of Sciences, he moved to Moscow with his laboratory in 1934. With the beginning of the German-Soviet war in 1941 it was transferred to the Sverdlovsk region, where research work on piezoelectricity continued. In 1943 he returned to Moscow with his laboratory, and in 1944 it was transformed into the Institute of Crystallography by a decision of the Presidium of the Academy of Sciences. In 1953 he founded the Department of Crystal Physics at the Physics Faculty of Lomonosov University and was a professor there until 1968. He served as director of the academy's Institute for Crystallography until 1962.

Shubnikov was a corresponding member of the Academy of Sciences of the USSR from 1933, and a full member and academician from 1953. Shubnikov was a co-founder of the International Union of Crystallography. Shubnikov was a foreign member of the mineralogical societies of Great Britain and of France.

He is known for his research in the 1950s on the Shubnikov groups named after him, with many applications in crystallography and solid-state physics, especially in the fields of magnetism and ferroelectricity. These groups were introduced by Heinrich Heesch in 1929 and are therefore also called Heesch-Shubnikov groups today.

Works
Shubnikov was the author of more than 250 scientific publications. His main works are devoted to the theory of symmetry, the theory of crystal growth, and the physical properties of crystals. He was the first to draw attention to piezoelectric textures, which predicted the possibility of visual observation of atoms and molecules when monochromatic rays pass through two superimposed crystal rasters, which has found application in the technique of modern electron microscopy. Having developed the doctrine of antisymmetry, he deduced the 58 crystallographic point groups of antisymmetry (Shubnikov groups). Selected works available in English:
