Heinrich Gerhard Kuhn (10 March 1904 – 25 August 1994) was a British physicist. A graduate of the University of Göttingen, where he studied for his doctorate under the direction of James Franck, winner of the 1925 Nobel Prize for Physics, he left Germany after the Nazi Party came to power there in 1933, and moved to Britain, where relatives had settled, becoming a British subject in 1939. At the invitation of Frederick Alexander Lindemann, he worked for Imperial Chemical Industries at the Clarendon Laboratory in Oxford, where he studied hyperfine structure. During the Second World War, he worked on isotope separation for Tube Alloys and the Manhattan Project. He was the first physicist to become a fellow at Balliol College, Oxford, in 1950, and published textbooks on atomic spectra in German in 1934 and English in 1962.
