Grigory Samuilovich Landsberg (Григорий Самуилович Ландсберг) (January 22, 1890, Vologda - February 2, 1957, Moscow) was a Soviet physicist. Grigory S. Landsberg is a co-discoverer of inelastic ''combinatorial scattering of light'' used now in Raman spectroscopy. His major scientific contributions were in the fields of optics and spectroscopy.

Since 1934, he simultaneously worked also in the Physical Institute of the Academy of Sciences of the USSR. In 1951-57 he was Professor of the Moscow Institute of Physics and Technology. Landsberg conducted the pioneering studies on vibrational scattering of light in crystals since 1926. In 1928, G.S. Landsberg and L.I. Mandelstam discovered a phenomenon of ''combinatorial scattering of light'' (this phenomenon became known as Raman effect independently discovered by C. V. Raman and K. S. Krishnan in liquids). Landsberg discovered the fine structure in Rayleigh scattering. In 1931, he discovered a phenomenon of selective scattering of light. He laid the foundation to spectroscopy of organic molecules and to the studies on inter- and intra-molecular interactions in the gaseous, liquid and solid phases in the USSR. He founded a major school on atomic and molecular spectral analysis. He developed techniques for the spectral analysis of metals and alloys (USSR Government Prize, 1941), and for the analysis of complex organic mixtures, including motor fuels. He is the author of the famous course of "Optics", and editor of the most popular "Elementary Textbook on Physics" (Volumes 1-3, 7th Edition, 1971). He was Founder and Chairman of the Commission on Spectroscopy of the USSR Academy of Sciences, transformed later (1968) into the Institute of Spectroscopy of the Academy of Sciences. G.S. Landsberg was awarded two Orders of Lenin and several medals. New phenomenon that they discovered spread in the world,〔Selective Lichtstreuung in Quecksilberdampf, ''Physikalische Zeitschrift der Sowjetunion'', 1935, Bd 8, H. 4, S. 378 (with Mandelstam, L.I.)〕〔Optics, 4 ed. , M., L., 1957 (General Physics Course, Volume 3)〕〔Selected Reports, M., L., 1958 (Introduction by C.
