Nuclear physicist who also carried out important research in low-tempearature and high-temperature physics. Seconded to the Cavendish Laboratory, Cambridge from Russia in 1921, he stayed in England until 1934, when the Russian authorities refures to give him a return exit visa after a holiday there. He continued his scientific work and, as the inscription states, 'he was a whimsical and generous man who never forgot the College'. Dismissed from his posts in 1946, he was reinstated after Stalin's death in 1953. Awarded a Nobel Prize in 1978.
