Martin Rosenberg (12 December 1890 – 1942) known as Rosebery d'Arguto was a Polish singer and a political prisoner during the World War II occupation of Poland.
In Berlin-Neukölln, he took over a mixed choir of the workers' singers' movement that had existed since 1890 and transformed it into a choral society with high musical standards.
In the years that followed, the association, which soon called itself the "Rosebery d'Arguto" singing community, specialized in pedagogical work and helped working-class children to receive a musical education.
[3] With the repression of the workers' music movement after 1933, the Jew, disparagingly referred to by the National Socialists as "Martin Rozenberg", also came under increasing pressure.
In compliance with Hitler's order from the same year, according to which all Jews still in the Reich were to be deported to Auschwitz-Birkenau, Rosebery d'Arguto was also taken on a train to the extermination camp on October 19, 1942.
