Alfred G. Maddock (1917–2009; “Alfie” to his friends) was among the last survivors of the select group of British scientists who participated in the birth of nuclear energy. Educated as a chemist, during World War II he joined the team of Frédéric Joliot’s collaborators who were transferred to Canada. There he acquired expertise in the chemistry of uranium, protactinium, and plutonium. From that time on, his interest extended to all fields relevant to chemistry and radioactivity. For half a century he was a leading authority on radiochemistry.
