Helmut Grunsky (11 July 1904 – 5 June 1986) was a German mathematician who worked in complex analysis and geometric function theory. He introduced Grunsky's theorem and the Grunsky inequalities.¹

In 1936, he was appointed editor of Jahrbuch über die Fortschritte der Mathematik. In 1939 he was forced to leave this position after Ludwig Bieberbach accused him of employing Jewish referees in a notorious letter.² He joined the Nazi Party on 1 April 1940, though he seems to have had little sympathy with its philosophy.³ He published in the journal Deutsche Mathematik. From 1949 he was Privatdozent at the University of Tübingen; later, he was professor at the University of Mainz and at the University of Würzburg.
