Nikolai Semyonovich Kurnakov (Russian: Николай Семёнович Курнаков; 6 December 1860 – 19 March 1941) was a Russian chemist, who is internationally recognized as the originator of physicochemical analysis. He also was one of the principal founders of the platinum industry in the USSR. A chemical reaction that he pioneered, known as the Kurnakov test, is still used to differentiate cis from trans isomers of divalent platinum and is his best-known contribution to coordination chemistry.
