Norbert Wolfgang Stephan Hann von Hannenheim (15 May 1898, Nagyszeben – 29 September 1945 in the Landeskrankenhaus Obrawalde near Międzyrzecz) was an Austro-Hungarian-born German composer.
A member of the Saxon community in Transylvania, Hannenheim was born in the city of Nagyszeben (in German: Hermannstadt, present-day Sibiu).
In 1925, in the competition for the "George Enescu-Preis", Hannenheim won the "Zweiten Nationalpreis für Komposition" ("Second national prize for composition").
Hannenheim was then a pupil in Schoenberg's Master Class in Composition at the Prussian Academy of Arts in Berlin (1929 to 1932).
His "2. piano concerto with small orchestra" in one movement was very successful and was broadcast by many radio stations all over the world.
It was long believed that Hannenheim perished in an Allied air raid on Berlin and that all his scores were destroyed, but numerous songs, piano sonatas and string quartets have come to light in recent years.
He survived the Nazi regime, but died some four months after the war ended, from heart disease (according to the death certificate).
