Charles Alfred Coulson died in Oxford (England). Born in 1910 in Dudley (Yorkshire), he was a chemical physicist who studied at Cambridge and first became a professor of theoretical physics in London, then a professor of mathematics, and finally a professor of theoretical chemistry at Oxford. He proposed the first theoretical models of molecular orbits that examined molecules as a unified object. He had many social and philosophical interests, which he channeled into humanitarian activities. His religious reflections are recounted in Christianity in an Age of Science (Oxford University Press, 1953) and Science and Christian Belief (Oxford University Press, 1955). He has been written about by David and Eileen Hawkin in The Word of Science: The Religious and Social Thought of C.A. Coulson (Epworth Press, 1989).
