Douglas Northcott

Northcott was born Douglas Geoffrey Robertson in Kensington on 31 December 1916 to Clara Freda (née Behl) (1894-1958) and her first husband Geoffrey Douglas Spence Robertson (1894-1978). His mother remarried in 1919 to Arthur Hugh Kynaston Northcott (1887-1952). In 1935, he legally adopted his step-father's surname.[1]

He was educated in London, then at Christ's Hospital and St John's College, Cambridge, where he started research under the supervision of G.H. Hardy

His work was interrupted by active service during World War II. Captured at Singapore, he survived his time as a prisoner of war in Japan, and returned to Cambridge at the end of the war.

Back at Cambridge, he published his dissertation "Abstract Tauberian theorems with applications to power series and Hilbert series ".[3][4] He then turned to algebra under the influence of Emil Artin, whom he had met while visiting Princeton University. He became a Research Fellow of St John's College in 1948.

In 1952, he moved to the Town Trust Chair of Pure Mathematics at Sheffield University. He remained at Sheffield until his retirement in 1982, also serving as Head of Department and Dean of Pure Science.

In 1954, Douglas Northcott and David Rees introduced in a joint paper[5] the Northcott-Rees theory of reductions and integral closures, which has subsequently been influential in commutative algebra.[6]

Northcott was awarded the London Mathematical Society Junior Berwick Prize in 1953 and served as LMS Vice-President during 1968-69. He was elected Fellow of the Royal Society in 1961.

In 1949, at Cambridge, Northcott married Rose Hilda Austin (1917-1992), with two daughters, Anne Patricia (born 1950) and Pamela Rose (1952-1992).
