During the Second World War, Rees was active on Enigma research in Hut 6 at Bletchley Park.[5][6] Education and careerRees was born in Abergavenny. He won a scholarship to Sidney Sussex college, Cambridge. At some stage, his university career took a backseat as he was drafted into Hut 6, Bletchley Park for the war effort. On completion of his education, he initially worked on semigroup theory, and Rees factor semigroup is named after him. He also gave a characterisation of completely simple and completely 0-simple semigroups, nowadays known as Rees's theorem. The matrix-based semigroups used in this characterisation are called Rees matrix semigroups.[3][7] At the behest of Douglas Northcott he switched his research focus to commutative algebra.[8] In 1954, in a joint paper with Northcott, Rees introduced the Northcott-Rees theory of reductions and integral closures which has subsequently been influential in commutative algebra.[9] In 1956 he introduced the Rees decomposition of a commutative algebra. Before 1960, Rees and his family moved to the University of Exeter, where their fourth child was born. Before 1971, Rees was appointed head of the Mathematics Department at the University of Exeter. Awards and honoursIn 1993 Rees was awarded the Pólya Prize by the London Mathematical Society. In August 1998 a conference on Commutative Algebra was held at Exeter in honour of David Rees' 80th Year. He was an Honorary Fellow of Downing College, Cambridge[10]. He was elected a Fellow of the Royal Society (FRS) in 1968.[4] Personal lifeIn 1952, he married Joan S. Cushen,[11] who became a Senior Lecturer in Mathematics at Exeter, with four children:
