Edward David Hughes

Edward David Hughes (June 18, 1906 – June 30, 1963) was a British organic chemist. He was a professor first at University College, Bangor and then at University College in London, eventually rising to the rank of dean at each. He was elected as a Fellow of the Royal Society in 1949.

Hughes studied organic reaction mechanisms and reaction kinetics, including being one of the first chemists to use isotopes to understand them. He collaborated with Christopher Kelk Ingold, leading to development of the eponymous Hughes–Ingold rules and Hughes–Ingold symbols.
