Werner Wolfgang Rogosinski FRS (24 September 1894 Breslau – 23 July 1964 Aarhus) was a British mathematician.[1]

His father, Hermann Rogosinski was Counsel in Wroclaw. Wolfgang Werner Rogosinski studied at Mary Magdalen School, from 1900 until1913 went. He then studied at the University of Breslau, University of Freiburg and University of Göttingen, with Edmund Landau. The study was interrupted by the World War I, in which Rogosinski served as a medic. He focused his studies on pure mathematics, and he also studied physics and philosophy. His interest was analytical problems, especially in series. His dissertation, "New Application of Pfeiffer's method for Dirichlet's divisor problem", caused a stir in 1922, for the mathematical professionals. Rogosinski married in 1928 in Königsberg. In 1932, his son Peter was born.
In 1923, he went to Koenigsberg, first as a lecturer and associate professor in 1928. There followed five productive and successful years working with Richard Brauer, Gabor Szego and Kurt Reidemeister. The Rogosinski and Szego families became friends. His first book was published in 1930. It was an introduction to Fourier series, and was written for students. The original was translated into English in 1959, and is still used today.
But after the takeover by the Nazis, everything changed. In 1936, his teaching credentials were withdrawn. He was allowed only in some Jewish schools in Berlin. The Cambridge professor G. H. Hardy, and John Edensor Littlewood, who were for some time in contact with Rogosinski, invited him to come to England. And so he lived beginning in 1937, thanks to generous support from the Society for the Protection of Science and Learning, with his wife and child in Cambridge, where he published with Hardy and Littlewood.
With GH Hardy, he published five papers from 1943 to 1949, under the title Notes on Fourier series. He was a teacher in Aberdeen in 1941, which gave him his own modest income and the opportunity to continue to work scientifically and to publish the results. In 1945, he went as a lecturer to Newcastle University; in 1947, he was appointed professor, and in 1948 Head of Department. During the years in Newcastle "Rogo" made contacts with other mathematicians.
In 1959, Rogosinski resigned from his position at Newcastle. Svend Bundgaard brought him into the Mathematical Institute, at Aarhus. In Denmark he was as popular as anywhere else. In 1954, he was elected Fellow of the Royal Society. In 1962, he was elected foreign member of the Royal Danish Academy of Sciences. His intention from Aarhus to Brighton was to go on to the new University of Sussex. He died after a long illness at the age of 69 years in Aarhus.
