The author of this report, Wilhelm Wortmann (born November 20, 1797 in Elberfeld, died August 6, 1882 in Dusseldorf) had been one of the deputy mayors in Dusseldorf since 1848 and was a member of the administrative council of the Allgemeine Musikverein, founded in 1845, where he functioned as recording secretrary. In addition, he was second oboist of the society's orchestra. This circumstance could have a personal note, since Wortmann was not a professional musician but one of the "dilletantes" whom Schumann disliked having in the orchestra.
