Veniamin Grigorievich (Benjamin) Levich (Russian : Вениами́н Григо́рьевич Ле́вич ; 30 March 1917 – 19 January 1987) was a Soviet dissident, who was an internationally prominent physical chemist, electrochemist and founder of the discipline of physico-chemical hydrodynamics. He was a student of the theoretical physicist, Lev Landau. His landmark textbook titled Physicochemical Hydrodynamics is widely considered his most important contribution to science. The Levich equation describing a current at a rotating disk electrode is named after him. His research activities also included gas-phase collision reactions, electrochemistry, and the quantum mechanics of electron transfer.
