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

Rogosinski focused his studies on pure mathematics, physics and philosophy.

His dissertation, "New Application of Pfeiffer's method for Dirichlet's divisor problem", caused a stir in 1922.

He worked with Richard Brauer, Gábor Szegő and Kurt Reidemeister for five years.

The Cambridge professors G. H. Hardy and John Edensor Littlewood invited him to come to the United Kingdom.

He moved with his wife and child to Cambridge in 1937, with support from the Society for the Protection of Science and Learning.
