Morris Sugden
Sir Theodore Morris Sugden FRS, (31 December 1919 – 3 January 1984) was a British chemist who specialised in combustion research. Biography

Theodore Morris Sugden (Morris) was born in the village of Triangle, the only child of Florence (née Chadwick) and Frederick Morris Sugden, a clerk in a mill. After attending Sowerby Bridge and District Secondary School he gained an open scholarship to Jesus College, Cambridge in 1938, where he read chemistry and was awarded a First in 1940. That year he began research under physicist W C Price on the measurement of precise ionization potentials of molecules. He later switched to working with R G W Norrish for war-work on the suppression of gun flash. Sugden’s later research activities were in the fields of flame studies, flame photometry, ionization in flames, and microwave spectroscopy. Appointments
