Stepan Sergeevich Batsanov was born in Moscow (November 9, 1928), obtained his MSc in Chemistry (1951); PhD on crystal-optical determination of the structure of complexes (1954) from Moscow State Universit. He received his DSc on refractometric methods in structural chemistry (1962) at Novosibirsk University, where he later became Chair in physical chemistry (1965). His main scientific interests are crystal optics, chemical structure and bonding, and (from 1966) shock-pressure chemistry and physics. He was the founder and director (in 1970-2010) of the Centre for High Dynamic Pressures (CHDP) at the State Committee of Standards at Mendeleevo, near Moscow. He authored and co-authored over 500 scientific papers and 8 books, including Structural Refractometry (in Russian, 1959, 2nd ed. 1976, English editions by Consultants Bureau, New York, 1961 & Van Nostrand, 1966), Effects of Explosions on Materials (Springer Verlag, 1994) and Introduction to Structural Chemistry (Springer, 2012).
