British physicists

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.

Archibald "Archie" Howie (born 8 March 1934) is a British physicist and Emeritus Professor at the University of Cambridge, known for his pioneering work on the interpretation of transmission electron microscope images of crystals. Born in 1934, he attended Kirkcaldy High School and the University of Edinburgh. He received his PhD from the University of Cambridge, where he subsequently took up a permanent post. He has been a fellow of Churchill College since its foundation, and was President of its Senior Combination Room (SCR) until 2010.
In 1965, with Hirsch, Whelan, Pashley and Nicholson, he published the seminal text Electron Microscopy of Thin Crystals. He was elected to the Royal Society in 1978 and awarded their Royal Medal in 1999. In 1992 he was awarded the Guthrie Medal and Prize. He was elected an Honorary Fellow of the Royal Society of Edinburgh in 1995. He was head of the Cavendish Laboratory from 1989 to 1997.
