in 1944. He was demobilized in September 1945 in Vienna. After the war, Galperin finished his studies and started his scientific career as a junior laboratory assistant at the Institute of Earth Physics of the USSR Academy of Sciences, where he later pursued his doctoral studies and became professor. He married Rimma Mikailovna in 1962 with whom he had two children, Adam (born 1962) and Sasha (born 1963). Galperin introduced the symmetric triaxial

design, which became widely used in exploration geophysics and seismology. The symmetric triaxial design is commonly known as the “Galperin configuration”, named after his inventor. Galperin also contributed significantly to the development of the Vertical Seismic Profiling (VSP) technique, which found little application outside the Sovjet union before mid-1970s but became a standard method in exploration seismology worldwide. Evsey Galperin became ill during the 1990 annual convention of the Society of Exploration Geophysicist (SEG) in San Francisco. He returned to Moscow and died less than a month later.
