A Dictionary of Music and Musicians/Nissen, Georg von
NISSEN, Georg Nicolaus von, Staatsrath of Denmark, was born at Hardensleben (Denmark), Jan. 22, 1761. When chargé-d'affaires at Vienna in 1797 he made the acquaintance of Mozart's widow, assisted her in regulating her embarrassed affairs, and, in 1809, married her. Retiring from official life in 1820 he settled in Salzburg, where he died March 24, 1826. His biography of Mozart, compiled from the mass of documents then in existence, and from the recollections of his wife and Mozart's sister, was published after his death by his widow, with preface by Dr. Feuerstein of Pirna, and 'Anhang' (published by Breitkopf & Härtel, with 2nd and cheap edition by G. Senff, Leipzig, 1828).
