Thread: 'A Violin Once Owned by Goebbels Keeps Its Secrets'

Alfred Rosenberg was head of the Sonderstab Musik (mentioned in linked article), a special Nazi 'task force' for music that was responsible for plundering the musical treasures (musical manuscripts, books and instruments) of deported and murdered Jewish communities, as well as those of occupied lands. As commissioner for the Entire Intellectual and Ideological Training and Education of the Party, his organization actively encouraged the involvement of German musicologists in Nazi activities and the expansion of the Reich. His office was an important source of funding for musicological research on the subject of race.
He was executed at Nurenburg.
