Friedrich Christian Accum or Frederick Accum (29 March 1769 – 28 June 1838) was a German chemist, whose most important achievements included advances in the field of gas lighting, efforts to keep processed foods free from dangerous additives, and the promotion of interest in the science of chemistry to the general populace. From 1793 to 1821 Accum lived in London. Following an apprenticeship as an apothecary, he opened his own commercial laboratory enterprise. His business manufactured and sold a variety of chemicals and laboratory equipment. Accum, himself, gave fee-based public lectures in practical chemistry and collaborated with research efforts at numerous other institutes of science.
