Caption: Nikolai Nikolayevich Semyonov (1896-1986), Russian-Soviet chemist Nobel Laureate. Semyonov was born at Saratov and educated at the University of Petrograd. After brief service during the Russian revolution he returned to Petrograd to teach. In 1931 he established the Institute of Chemical Physics at the Soviet Academy of Sciences and became its first director. His research was mainly concerned with the mechanisms of chemical transitions. The step-wise approach was to lead to an understanding of chemical chain reactions and to processes such as combustion. He shared the Nobel Prize in Chemistry in 1956 with Sir Cyril Hinshelwood. Photographed in 1976.
