TSENTNERSHVER Mechislav Gavrilovich (1874, Warsaw – 1944, ibid.), physical chemist. Doctor of Philosophy (1898), professor (1917), member of the Kraków Academy of Sciences (1931). After completing his studies at the University of Leipzig (1898) he worked at the Riga Polytechnic Institute (from 1917 as professor), then at the University of Latvia (1919–29). From 1929 professor at the University of Warsaw. His principal scientific works concern chemical kinetics, metal corrosion, and electrolysis. He investigated the electrical conductivity and other properties of non-aqueous solutions. He developed (1903–09) new methods for determining the critical parameters of liquids. He studied the kinetics of the dissolution of metals in acids. He worked on the history of chemistry.
