Sir Frederick Augustus Abel, (born July 17, 1827, Woolwich, London, Eng.—died Sept. 6, 1902, Westminster, London), English chemist and explosives specialist who, with the chemist Sir James Dewar, invented cordite (1889), later adopted as the standard explosive of the British army. Abel also made studies of dust explosions in coal mines, invented a device for testing the flash point of petroleum, and found a way to prevent guncotton from exploding spontaneously.
Abel studied chemistry at the Royal Polytechnic Institution and in 1845 became one of the original 26 students of A.W. von Hofmann at the Royal College of Chemistry. In 1852 he was appointed lecturer in chemistry at the Royal Military Academy in Woolwich, succeeding Michael Faraday, who had held that post since 1829. From 1854 until 1888 Abel served as ordnance chemist at the Chemical Establishment of the Royal Arsenal at Woolwich, establishing himself as the leading British authority on explosives.
