David Rees ScD Cantab, FIMA, FRS (Mathematics) (born 28 May 1918) is an emeritus professor of pure mathematics at the University of Exeter, having been head of the Mathematics / Mathematical Sciences Department at Exeter for many years.

During the Second World War, Rees was active on Enigma research in Hut 6 at Bletchley Park.

He initially worked on semigroup theory, and Rees factor semigroup is named after him. He also gave a characterization of completely simple and completely 0-simple semigroups, nowadays known as Rees's theorem. The matrix-based semigroups used in this characterization are called Rees matrix semigroups.^[1][2]

At the behest of Douglas Northcott he switched his research focus to commutative algebra.^[3] 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.^[4]

In 1993, he 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 is an Honorary Fellow of Downing College, Cambridge ^[5]

Family

In 1952,^[6] he married Dr Joan S. Cushen, who, as Dr Joan Rees, became a Senior Lecturer in Mathematics at Exeter, with several children, including:

1. Professor (Susan) Mary Rees FRS, Professor of Mathematics at the University of Liverpool, b. 1953 ^[7][8][9]
2. Rebecca Rees, b. 1955 ^[10]
3. Professor Sarah E. Rees, Professor of Pure Mathematics at Newcastle University, b. 1957 ^[11][12]
4. Deborah Rees, b. 1960 ^[13]
