100th Anniversary of the Department of Crystallography of St. Petersburg State University: Pages of History

The major milestones in the centennial history of the Department of Crystallography of St. Petersburg State University, the oldest of the existing departments of crystallography in Russia, are considered. It is shown that the St. Petersburg scientific crystallographic school originates from the great Russian scientist E.S. Fedorov (1853–1919). The main areas of the scientific activity of the staff (crystal morphology, crystal optics, crystal growth, crystal chemistry, crystal physics, X-ray diffraction analysis) are described, and biographical information about the heads of the department (O.M. Ansheles, V.B. Tatarsky, V.A. Frank-Kamenetsky, S.K. Filatov, Y.O. Punin) is given.
