Person: Kuttner, Brian
Brian Kuttner was an English mathematician who worked on Fourier Series.
Mathematical Profile (Excerpt):
 Brian Kuttner attended University College School in London and from there he won a scholarship to study at Christ's College Cambridge.
 Kuttner spent a while in Göttingen studying with Edmund Landau and received his doctorate in 1934.
 However, before the award of his doctorate Kuttner had been appointed in 1932 as an assistant lecturer at the University of Birmingham.
 At Birmingham Kuttner joined the Mathematics Department headed by G N Watson.
 Most of Kuttner's early work is on Fourier series and summability.
 Hardy quotes some of these early results of Kuttner's in his treatise Divergent series (1949).
 at the age of only 26, Kuttner proved a basic theorem in the general theory of trigonometric series, a result delightful for both the deceptive simplicity of its statement and the elegance of its proof.
 Zygmund greatly admired this theorem of Kuttner, which now occupies an honoured place in Zygmund's monumental work on trigonometric series.
 Kuttner's interests outside mathematics included travelling and walking.
Born 11 April 1908, London, England. Died 2 January 1992, Birmingham, England.
