Werner Wolfgang Rogosinski

Werner Wolfgang Rogosinski (1894 to 1964), known to friends as Rogo, was a pure mathematician who worked on the theory of functions and of series, above all Fourier series. Born in Breslau, then a German town, he studied at Breslau, Freiburg and Göttingen, where his doctoral research was directed by Edmund Landau and concerned the Dirichlet divisor problem. He was appointed at Königsberg in 1923 and collaborated there with Gábor Szegő. Dismissed in 1936 under the Nazi laws, he was brought to Cambridge in 1937 by G. H. Hardy and J. E. Littlewood. After posts at Aberdeen and Durham he held the chair of pure mathematics at King's College, Newcastle, from 1948. With Hardy he wrote the Cambridge tract Fourier Series (1944) and he also wrote Volume and Integral (1952). He became a Fellow of the Royal Society in 1954, joined the Danish Academy of Sciences in 1962, and died in Aarhus.
