Sir Theodore Morris Sugden FRS, (31 December 1919 – 3 January 1984) was a British chemist who specialised in combustion research.[1] [2]
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.[3] [1]
Sugden married Marian Florence Cotton in 1945. They had one child, Andrew Morris, born in 1954. He graduated from Oxford in Botany in 1975, and later gained a doctorate in tropical rainforest ecology. He undertook an expedition to the Serranía de Macuira in northern Colombia, publishing a checklist to the plants of this area along with Enrique Forero. He has subsequently followed an editorial career.[4]
Sir Theodore Morris Sugden died at Addenbrooke's Hospital, Cambridge on 3 January 1984; he was cremated in Cambridge on the 10th. The Sugden Award for combustion research is named in his honour.
Lady Marian Sugden died in December 2009.[5]
