Sir Arthur McDougall Duckham GBE KCB (8 July 1879 – 14 February 1932) was one of the founders of the Institution of Chemical Engineers, and its first president. Duckham was born in Blackheath, London, the second son of a Falmouth-born mechanical and civil engineer, Frederic Eliot Duckham (1841 – died 13 January 1918 in Blackheath), who had patented improvements in governors for marine engines and invented a 'Hydrostatic Weighing Machine'. His mother was Maud Mary McDougall (1849–1921), sister of John McDougall of the flour-making family, which had a mill at Millwall Dock. His older brother was Alexander Duckham, notable for the development of machine lubricants.
